    Dr. Mary Bourke from Trinity College Dublin have discovered a patch of land in an ancient valley in Mars’ Lucaya Crater that appears to have held water in the not-too-distant past, making it a prime target to search for past life forms on the Red Planet. Signs of water past and present pop up everywhere on Mars from now-dry, wriggly riverbeds snaking across arid plains to water ice exposed at the poles during the Martian summer. ... “On Earth, desert dune fields are periodically flooded by water in areas of fluctuating groundwater, and where lakes, rivers and coasts are found...

    Ceres, one of five dwarf planets in the solar system, is also an asteroid — the largest of them, in fact. Formed around 4.5 billion years ago, it sits in the belt of rocky debris that lies between the orbits of Mars and Jupiter. ... Among the asteroids, Ceres is special. As a dwarf planet, it got stuck somewhere along the way to becoming a full-grown world. Frozen in this state, Ceres also offers a snapshot of planetary adolescence. Scientists have long wondered whether asteroids had not just water but also organic matter that could have been brought to Earth,...

    o radar imager Lance Benner at JPL in Pasadena, asteroid 2017 BQ6 resembles the polygonal dice used in Dungeons and Dragons. But my eyes see something closer to a stepping stone or paver you’d use to build a walkway. However you picture it, this asteroid is more angular than most imaged by radar. It flew harmlessly by Earth on Feb. 7 at 1:36 a.m. EST (6:36 UT) at about 6.6 times the distance between Earth and the moon or some about 1.6 million miles. Based on 2017 BQ6’s brightness, astronomers estimate the hurtling boulder about 660 feet (200 meters) across....

    The NASA-employed Science Definition Team has been crafting a plan to launch a mission that would search for alien life on Jupiter's icy moon Europa. The extraterrestrial world of Europa is considered as among the most likely places in the solar system to have the ability to support life as we know it. Scientists have gathered evidence that the salty ocean that lurks beneath the icy crust of the moon could be hospitable to life. Recent models also hint that the icy world can produce oxygen and hydrogen, which suggests it may have the necessary energy to support life.

    A stray black hole may be responsible for turning a gas cloud into a speeding cosmic bullet trillions of miles long. The wandering black hole was discovered lurking just outside a supernova remnant, a shell of expelled material left behind after a massive star explodes. Using the Atacama Submillimeter Telescope Experiment (ASTE) in Chile and the 45-meter (148 feet) Radio Telescope at Nobeyama Radio Observatory, astronomers found that the black hole had been previously hidden by a compact gas cloud emerging from the remnant. The cloud itself has now been named "the Bullet," because of its long, cone shape and...

    Stay away from Europa? No way. It’s just too fascinating a place with its jigsaw-puzzle ice sheets, crisscross valleys, miles of ice on top and a warm, salty ocean below. The movie was prescient — if you’re going to search for life elsewhere in the solar system, Europa’s one of the best candidates. While we’ve sent spacecraft to photograph and study the icy moon during orbital flybys, no lander has yet to touch the surface. That may change soon. In early 2016, in response to a congressional directive, NASA’s Planetary Science Division began a pre-Phase A study to assess the...

    They move so slowly that a human lifetime is a tiny blip compared to them. This makes their orbit essentially unobservable. But astronomers were able to find the next best thing: the often predicted but never observed stellar stream, or bridge of stars, stretching between the two clouds. A star stream forms when a satellite galaxy feels the gravitational pull of another body. In this case, the gravitational pull of the LMC allowed individual stars to leave the SMC and be pulled toward the LMC. The stars don’t leave at once, they leave individually over time, forming a stream, or...

    A chance observation in a corner of the Milky Way galaxy could hint at a hidden black hole. A cloud travelling in a corner of our galaxy at a blistering 100 kilometres per second likely harbours a black hole, according to Japanese astronomers. Masaya Yamada and colleagues from Keio University mapped the motion and appearance of the fast-moving feature – nicknamed the "Bullet" – and concluded that its shape and velocity can be attributed to a black hole hiding within. The work, which was published in The Astrophysical Journal, outlines one of only a few such "quiet" black holes found...

    For 10 days this month, OSIRIS-REx will investigate whether or not Trojan asteroids exist at certain points in Earth’s orbit called Lagrange points. Though Jupiter has Trojan asteroids, it’s unclear whether or not Earth’s Lagrange points host similar objects. After all, only one Earth Trojan has ever been found. “The Earth orbits around the Sun, and the Earth has a gravitational field and the Sun has a gravitational field,” explained Dante Lauretta, OSIRIS REx’s principal investigator. “Because of that property, there are certain points in space where those two fields balance each other out, called Lagrange points.” OSIRIS-REx will be...

    August 24, 2006 was a dark day for Pluto enthusiasts. It was on that day that the International Astronomical Union established three conditions a celestial body must meet in order to be considered a planet. A planet must orbit around the sun, it must be massive enough to be rounded by its own gravity, and it must have “cleared the neighborhood” around its orbit, which means, simply put, that it must have a certain amount of gravitational pull. Pluto does not meet the third condition, so once those rules were put in place, Pluto was demoted to “dwarf planet,” 75...

Chondrites are further divided into three classes: H, L and LL, each thought to correspond to a different impact event long ago. We’re currently seeing a disproportionate number of H and L-type chondrites hit the Earth, but, it wasn’t always so. Looking at a slice of time around a million years before the event, the researchers took a census of the meteorites that intersected the Earth’s orbit, and found that...

    When you think about our Solar System, with its lone, luminous star dominating both the mass and light of our local corner of the Milky Way, you might think that this is what 'typical' looks like. In some ways, this is true, but a Solar System with multiple stars -- binaries, trinaries or more -- might be even more common. At interstellar distances, many of these binaries are too close together to resolve even with the most powerful of telescopes. Instead, it's only the variations in their light, where the stars more relative to one another, periodically eclipse (passing in...

New research published today by a global team of researchers, based at the International Centre for Radio Astronomy Research (ICRAR), seeks to answer that question.

By looking at the largest cosmic scales and the oldest signals -- the leftover radiation from the Big Bang and the largest-scale galaxy correlations -- we get one number for the rate: 67 km/s/Mpc. But if we look at individual stars, galaxies, supernovae and other direct indicators, we get another number: 74 km/s/Mpc. The uncertainties are very...

Yet new research from the Weizmann Institute of Science in Israel has put forward a theory that the Moon may have actually formed from a series of large impacts, rather than just one. The study, published in the journal Nature Geoscience, explains why the Moon appears to be made mostly from Earth-like materials, rather than a mixture of our elements and those of another mystery planet.

    NASA recently spotted two massive space objects hurtling towards Earth. While the American space agency has pinpointed one as a comet, the other has left it slightly more baffled. The comet is set to fly close to Earth this week, but the mystery object isn't expected to make an appearance until February. The object, dubbed "2016 WF9", was detected by NASA's asteroid- and comet-hunting NEOWISE project on 27 November 2016. It is roughly 0.3 to 0.6 miles (0.5 to 1 kilometres) across and is in an orbit that takes it on a scenic tour of our solar system. At its...

    Seeing Comet C/2016 U1 NEOWISE fly by would be a rare opportunity for skygazers because the celestial body won't likely pass by Earth for the next thousands of years. Unlike short period comets such as Halley's, a comet which passes by our planet every 75 to 80 years, it would take C/2016 U1 NEOWISE far longer time before it gets to visit this region of the solar system again. ... Paul Chodas, from NASA's Center for Near-Earth Object (NEO) Studies, said that there is a good chance that the object will be visible from Earth using a good pair of...

    Among the many eye-catching astronomical shows coming up, 2017 may be best remembered for the much anticipated total eclipse of the sun that will cross the continental United States in August. In addition to that spectacular sight, sky-watchers will have a plethora of treats to look forward to in the coming months. To kick things off, an icy comet will swing by Earth in February, hopefully offering picturesque views. Elusive Mercury and giant Jupiter will both put their best faces forward as they appear their biggest and brightest early in the year. And in December, the annual Geminid meteor shower...

    Some Hindus are calling the New Years Eve Comet, known officially as Comet Honda-Mrkos-Pajdušáková, that will be just next to the crescent moon this New Years Eve, the "Trump Comet". This amazing greenish comet with fan tail which, with a good eye or better yet a pair of binoculars, will be seen near the crescent moon on this coming New Years Eve on the Western horizon after the sun sets. And it will be visible again even brighter in February 2017 to Welcome Donald J Trump the New President!

    From any point on Earth's surface, a clear night sky reveals a treasure trove of stars and deep-sky objects. Through a powerful telescope, billions of objects become visible, from stars and nebulae to the galaxies beyond our own. With the success of the Hubble deep fields in revealing distant, hitherto unseen galaxies, 2010 brought a new camera and a new ambition. The installation of the Wide Field Camera 3 enabled simultaneously large, deep views of space as never before. The Great Observatories Origins Deep Survey (GOODS) began with this 2010 mosaic, which stitched together hundreds of images in visible and...

    While we’ve been shopping for gifts the past few weeks, a returning comet has been brightening up in the evening sky. Named 45P/Honda-Mrkos-Pajdusakova, it returns to the hood every 5.25 years after vacationing beyond the planet Jupiter... Comet 45P is a short period comet — one with an orbital period of fewer than 200 years — discovered on December 3, 1948 by Minoru Honda along with co-discoverers Antonin Mrkos and Ludmila Pajdusakova. Three names are the maximum a comet can have even if 15 people simultaneously discover it. 45P has a history of brightening rapidly as it approaches the sun,...

    What will happen to Earth when, in a few billion years' time, the Sun is a hundred times bigger than it is today? Using the most powerful radio telescope in the world, an international team of astronomers has set out to look for answers in the star L2 Puppis. Five billion years ago, this star was very similar to the Sun as it is today. "Five billion years from now, the Sun will have grown into a red giant star, more than a hundred times larger than its current size," says Professor Leen Decin from the KU Leuven Institute of...

    THE SOLAR WIND CONTINUES TO BLOW: For the third day in a row, Earth is inside a stream of solar wind blowing out of a large hole in the sun's atmosphere. This is causing magnetic unrest and bright auroras around the poles. NOAA forecasters estimate a 35% chance of G1-class geomagnetic storms on Dec. 24th. WHITE AURORAS? Auroras are usually green. Occasionally, other colors appear: red, purple, blue. One color that never shows itself, however, is white--that is, not until last night. "I saw white auroras over Tromsř, Norway!" reports veteran observer Markus Varik.
