Problems with the mole ©NASA/JPL-Caltech Not every mission goes entirely to plan, and NASA’s Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) lander is no exception. This recent image taken by one of the onboard cameras shows part of an instrument that is meant to dig five metres (16 feet) into the Martian surface in order to measure the heat coming from within. This instrument, commonly referred to as ‘the mole’, has hit a snag, and can’t seem to dig further than about 0.3 metres (one foot). In this image it appears to have popped out of the ground after engineers tried pinning it to the wall of the hole using InSight’s robotic arm to increase friction.…

Up-close and personal with Jupiter © NASA/JPL-Caltech NASA’s Juno spacecraft is still flying around Jupiter, getting up-close and personal with the gas giant approximately every two months, but only for a brief period. These close encounters – known as a ‘perijove’ – mean the instruments are put to work to collect as much data as they can in a short time. Its JunoCam snaps as many photos as it can, and they are put onto the Juno website for members of the public to edit and enhance. This particular image was enhanced by citizen scientist Gerald Eichstädt, and it flaunts the entangled nature of jet streams in Jupiter’s northern hemisphere, known as ‘Jet N3’.…

Trick or treat? ©NASA/ESA Halloween always bares wicked faces and ghastly sights, but it’s not often they are seen in space. This isn’t a trick, but definitely a treat: NASA/ESA’s Hubble Space Telescope snapped this picture of two galaxies – both of equal size – caught in a gravitational tangle. The galactic collision in this Arp-Madore system, located 704 million light years from Earth, remarkably resembles a ghostly face, making it a perfect present for Halloween enthusiasts around the world.…

NASA’s Voyager spacecraft may only have five years left © NASA/JPL The twin Voyager probes have about five years before they fall silent, when they'll no longer be able to send word of their adventures back. The Voyagers' journey will continue indefinitely, but we will no longer travel with them. "It's cooling off. The spacecraft is getting colder all the time and the power is dropping," Ed Stone, the mission's project scientist and a physicist at Caltech, said during a news conference held on 31 October in conjunction with the publication of a handful of new scientific papers. "We know that somehow, in another five years or so, we may not have enough power to have any scientific instruments on any longer." Their success is unprecedented, even by NASA standards;…

NASA eyes a possible return to Pluto Words by Mike Wall NASA is thinking about going back to Pluto, this time to stay for a while. The space agency has funded the Southwest Research Institute (SwRI) to conduct a wide-ranging study into a possible Pluto orbiter mission. The study will lay out design and instrument requirements and investigate the feasibility and costs of the potential project, SwRI representatives said. SwRI leads NASA's New Horizons mission, which zoomed past Pluto in July 2015, snapping the first-ever up-close photos of the dwarf planet. The historic flyby revealed Pluto to be a surprisingly diverse and complex world, with 3.2-kilometre (two-mile) mountains of water ice and vast plains of nitrogen ice, among other features. On 1 January of this year, New Horizons conducted a…

Our hunt for another universe There have already been some hints that we live in a multiverse Is inflation an eternal process? Inflation – a period of rapid initial expansion – is a modification to the theory of the Big Bang which makes it easier to explain the resulting universe we observe. Most models of inflation suggest it is a never-ending process – where you get one universe you get many. Cosmic microwave background cold spot Most temperature variations in the CMB are small, yet there is an unusually large one in the Southern Hemisphere sky. Some researchers point to it as evidence of a collision between our universe and another, although that idea continues to be the subject of fierce debate. Planck Launch: 14 May 2009 Mission objectives: Map…

Focus on Martian habitats INSIDE A MARTIAN HABITAT What are humans going to live in once they’re on Mars? One New York company thinks it has the answer © Spacefactory Earlier this autumn, space.com visited the main offices of AI SpaceFactory, an architecture and technology design agency that specialises in designing and 3D-printing Martian habitats. The company recently competed in and won NASA's 3D-printed habitat challenge with a design called Marsha. AI SpaceFactory founder and CEO David Malott took space.com around this space factory to see what it really takes to build a Martian habitat. "The whole reason to do that is, it's too expensive to ship materials to Mars," Malott said to space.com. "We want a place for the astronauts to stay in," he added. When we are ready…

The theories There are various explanations for what it could be – and where it's come from A home-grown comet When Gennadiy Borisov first discovered the object on 30 August 2019, it was thought to have been born within our Solar System. Perceived to be a near-Earth object, it was given the designation gb00234 by the International Astronomical Union's Minor Planet Center and was later noted to be a comet, designated C/2019 Q4 (Borisov). © NASA An interstellar interloper Within two weeks scientists were already suspecting it was a comet from outside of our Solar System, even though it's similar to those born within. By 24 September 2019 the International Astronomical Union had given it the interstellar designation 2I/Borisov – following on from 1I/‘Oumuamua. This remains the most accepted explanation.…

Earth's explosive evolution DO WE NEED TO REWRITE EARTH’S HISTORY? From metal rains to devastating explosions, new discoveries and surprising theories are changing how we look at the early days of our planet Reported by Giles Sparrow © Shutterstock The era of Earth’s formation, alongside the other planets in orbit around the young Sun, has long been seen as a time of dramatic collisions and cataclysmic encounters between newborn planets, but new discoveries have suggested that conditions could have been even more violent than previously suspected. And according to one theory, the most devastating event in our planet’s entire history was triggered not by a chance encounter with a random rogue planet, but by a ticking timebomb beneath Earth’s own surface. Astronomers have pinned down the age of the Earth…

Earth's explosive evolution History of the Earth With over 4.5 billion years of history, Earth has gone through some remarkable changes to produce the hospitable planet we know today © Richard Bizley /Science Photo Library 14.54 billion years ago: the Earth forms Earth and the other rocky planets formed through violent collisions between planetesimals. The core formed rapidly as heavy elements filtered down through the mantle towards the centre of the planet, while bombardment continued to spread metallic elements across the surface. 24.5 billion years ago: origin of the Moon The Moon formed 50 to 100 million years after the Earth. The most popular current theory for the Moon’s formation involves a substantial part of the mantle being blasted away from Earth by a giant impact, but some argue that…

Sean Carroll QUANTUM MECHANICS 101 With a new book recently hitting shelves, Sean Carroll speaks to All About Space about the world of super strange physics and why there needs to be more attention on the subject Interviewed by Lee Cavendish Richard Feynman said about 50 years ago: “I think I can safely say that nobody understands quantum mechanics.” Is that still the case? I think that is the case as long as we interpret what he says in a certain way. What is absolutely the case is that physicists don't agree about quantum mechanics. Even if one physicist does understand it, nobody else thinks that they understand it. As a field I would say it's safe to say that physicists don't claim to understand quantum mechanics.

Celebrating a year in space © NASA NASA’s latest exoplanet hunter, the Transiting Exoplanet Survey Satellite (TESS), recently marked off its first anniversary of operations in space, which was celebrated by producing a mosaic image of the southern sky from TESS data. 18 July 2019 was the official anniversary of its first year of science operations, but it has taken a while to put together 208 TESS images to create this view of the southern night sky, divided into 13 sectors, showing the arc of our Milky Way.…

Cubesat shopping © ESA On display at a recent European Space Agency Antenna workshop was a replica of the agency’s Miniaturised Asteroid Remote Geophysical Observer, or M-Argo. This nanosatellite isn’t big enough to warrant its own space launch, so it will have to hitchhike a lift with a larger space mission going beyond the orbit of Earth. Once the suitcase-sized satellite is launched it will eventually rendezvous with asteroids and map their natural resources, such as hydrated minerals, which could potentially be harnessed for exploration missions in the future.…

India has a new planetary target in mind: Venus © ESA India is already eyeing a new destination. Scientists and engineers at the Indian Space Research Organisation (ISRO) have sent plans for a Venus orbiter to the Indian national government and are hoping they'll get approval to go ahead with the mission. The spacecraft could launch in just a few years and would carry more than a dozen instruments. "The major objective is to map the Venusian surface and subsurface," Nigar Shaji, an ISRO scientist, told a group of Venus experts during a meeting held this week in Colorado. According to Shaji, the Venus orbiter that ISRO is designing would be able to create such a dataset for Venus in about a year. In addition to mapping the surface itself,…

Sun as lens could check for alien life Words by Meghan Bartels © NASA Our Sun may be able to shed light on whether life is hiding on a distant planet, assuming humans can execute a delicate manoeuvre in space. Astrobiologists searching for signs of life beyond Earth target biosignatures, characteristics most likely caused by life. But scientists are excellent at hypothesising alternative, nonlife processes for creating biosignatures, which means identifying these characteristics on distant worlds isn't a guarantee you've found life. "We want to find a way to get closer," Sara Seager, an astronomer at the Massachusetts Institute of Technology, said. "We want to get another look. We don't really have any ways to do that now." Seager referenced one possible solution to that quandary: designing tiny satellites that…

What happens in other universes? Physicists have contemplated different levels of multiverse created by different physics processes © Tobias Roetsch Level I Even if there is only one universe, there could still be exact copies of this planet knocking around. As there are only a finite number of ways of arranging things, in an infinitely big universe repeats are guaranteed to occur. What happens inside this universe? Everything that happens in the observable universe is repeated an infinite number of times. Also, every possible combination of events can unfold an infinite number of times. There are planets where you don't exist, but also those where you do and you're the ruling monarch of the universe or a sentient slug – or even both. Level II The process of eternal inflation…

MYSTERIES OF THE UNIVERSE DOES COMET BORISOV HAVE ALIEN ORIGINS? A second interstellar interloper has been discovered within the Solar System, but it won’t be hanging around Reported by David Crookes © Tobias Roetsch Some mysteries have been perplexing astronomers for some time, while others have arrived on the scene only recently. In the case of the Solar System's newest guest, the latter is most certainly true. It was 30 August 2019 when amateur astronomer Gennadiy Borisov pointed his telescope skywards in Crimea, and what he saw that night not only amazed him, but sent fellow scientists scurrying for a look. Borisov's observation was extraordinary. “It was the most exciting discovery of 2019,” exclaims Paul Kalas, adjunct professor of astronomy at the University of California, Berkeley. What he discovered that…

Spot the comet Peer skywards at the right time with the right equipment and you may be able to observe Borisov from Earth Reaching its perihelion On 8 December, 2I/Borisov will reach its perihelion, making its closest approach to the Sun. At this stage it will be 300,000,000 kilometres (186,411,358 miles) from both the Sun and Earth. How visible it will be depends to a great extent on the coma's degree of condensation. Closest to Earth The comet will be closest to Earth on 28 December, when it will be about 1.9 AU away. This will be the best day to observe the comet, although it is likely to be at its brightest in the southern sky and peak at a magnitude of 15 – which makes it as faint…

Inside planet Earth Our world’s internal structure seems to be more complex than previously thought © Getty Asthenosphere In the upper part of Earth’s mantle, temperature and pressure weaken the strength of rock – it can be stretched more easily. Inner core Earth’s inner core is a mix of solid iron and nickel with some lighter and heavier elements. It is able to ‘superrotate’ at a rate slightly faster than Earth’s surface. Core-Mantle boundary The boundary between the core and the mantle is marked by a region of the lower mantle where rocks become molten. Mantle Earth’s mantle is dominated by silicate minerals that change their form at a transition zone around 500 kilometres (311 miles) down. Crust Earth’s outer crust is broken into tectonic plates that move slowly but…

Martian meteorite THE CURIOUS CASE OF ALH84001 35 years ago, a meteorite was discovered in Antarctica that changed the course of Martian exploration and investigation Reported by Lee Cavendish © Getty; Adrian Mann On 27 December 1984, a piece of rock was found in the Allan Hills region of Antarctica by the Antarctic Search for Meteorites (ANSMET) programme. What they originally identified as a mediocre meteorite turned out to be arguably the greatest catalyst in the field of astrobiology, and in particular the search for life on another planet. The rock, designated ALH84001 – ALH referring to Allan Hills – was left in the archives for about a decade after it was found, as the ANSMET team labelled it as a piece of leftover space rock from the formation of…

What is a quark? They make up all matter Quarks are elementary particles that form the components of the atomic nucleus’ protons and neutrons. They are therefore building blocks of all ordinary matter in the universe. They are ruled by gluons Quarks are governed by quantum chromodynamics (QCD), a theory that describes the ‘strong interaction’ between individual quarks through a force-carrier particle called the gluon. They come in different flavours We know quarks come in six different types, or flavours: up, down, strange, charm, bottom and top. They behave like a quantum spinning top Quarks have another property called spin that gives them a form of angular momentum, like a quantum spinning top. They don’t like their own company While combinations of three quarks form hadrons, and pairs form mesons,…

STARGAZER Planet of the month This month’s planets Venus, Jupiter and Saturn will form a bright planetary chain across the twilight sky this month Our ‘Planet of the Month’ this issue really deserves its title because it will look like a lantern blazing in the western sky over the festive period. Venus will be a gorgeous ‘evening star’, outshining everything else in the sky apart from the Moon and the Sun. Even after we move into 2020 it will continue to dominate the sky after sunset, appearing the most impressive it has for a long time. Being closer to the Sun than Earth, Venus is hotter than our world, but its thick, curdled atmosphere of carbon dioxide has inflicted brutal global warming on Venus for many millions of years, so its…

Deep sky challenge Tour beyond the Orion Nebula Track down some of winter’s lesser-known wonders on the next clear and frosty night ©NASA © ESO Just as it’s easy for them to return to the same ‘celestial celebrities’ night after night in the summer – the Ring Nebula, M13 and M51 all repeatedly draw the eye away from other things – the deep-sky observer’s winter comforts are the bright, swirling clouds of the stunning Orion Nebula and the glittering spectacle of the Pleiades. But there are many other objects in the winter sky just as – if not more – deserving of attention. And given that December nights are often beautifully clear and brutally cold, this is a good time to wrap up warm, head out and track down some…

LAUNCH PAD YOUR FIRST CONTACT WITH THE UNIVERSE Concentrating on the past © ESA/Hubble/NASA NASA/ESA’s Hubble Space Telescope is back at it again, this time capturing the curvature of a galaxy present during the universe’s Epoch of Reionisation. Four major arcs of light are present in this image, nicknamed the ‘Sunburst Arc’, because of a cosmic phenomenon known as gravitational lensing. This phenomenon takes the light of distant background galaxies and focuses it towards Earth due to the intense gravity of the foreground galaxy, curving it like a glass lens. An image such as this allows astronomers to probe the earliest years of the universe, roughly 150 million years after the Big Bang.…

LAUNCH PAD YOUR FIRST CONTACT WITH THE UNIVERSE An eye over the Atacama Desert © ESO The La Silla Observatory is one of the busiest observatories in the world, known for unveiling stunning sights from the depths of the cosmos. However, when photographers take a step back, the site itself can create some equally stunning pictures. In this instance, looking down on one of La Silla’s telescopes is the Moon with a 22-degree halo surrounding it. This occurs when light reflected by the Moon hits cirrus clouds high up in the atmosphere and the tiny ice crystals present within the clouds refract the light.…

A large majority of the globe – unfortunate for central and eastern Asia, Japan, Indonesia and Australia – had roughly six hours to catch the innermost planet’s path across the Sun’s surface. This rare sight put into context the journey ahead for the European and Japanese space agencies' highly anticipated Mercury mission, BepiColombo. This mission will be put into orbit around that miniscule silhouette in six years' time.…

LAUNCH PAD YOUR FIRST CONTACT WITH THE UNIVERSE The universe might be a giant loop Everything we think we know about the shape of the universe could be wrong. Instead of being flat like a bedsheet, our universe may be curved like a massive, inflated balloon. That's the upshot of a new paper published in the journal Nature Astronomy which looks at data from the cosmic microwave background (CMB), the faint echo of the Big Bang. But not everyone is convinced; the new findings, based on data released in 2018, contradict both years of conventional wisdom and another recent study based on that same CMB dataset. © ESA “Gravity seems to be bending the microwaves of the CMB more than existing physics can explain” If the universe is curved, according…

LAUNCH PAD YOUR FIRST CONTACT WITH THE UNIVERSE ‘Improbable planet’ somehow survives being swallowed by red giant star Words by Chelsea Gohd © NASA Using astroseismology data from NASA's Transiting Exoplanet Survey Satellite, or TESS, a team of researchers studying the red giant stars HD 212771 and HD 203949 detected oscillations. This is the first time that oscillations have been found by TESS in stars that host exoplanets. Because these stars have orbiting exoplanets, the investigation was able to go even deeper.
