NASA's Mars Reconnaissance Orbiter has identified new markings on the surface of the Red Planet that are believed to be related to ESA's ExoMars Schiaparelli entry, descent and landing technology demonstrator module.
A group of citizen scientists and professional astronomers joined forces to discover an unusual hunting ground for exoplanets. They found a star surrounded by the oldest known circumstellar disk -- a primordial ring of gas and dust that orbits around a young star and from which planets can form as the material collides and aggregates.
Essential data from the ExoMars Schiaparelli lander sent to its mothership Trace Gas Orbiter during the module's descent to the Red Planet's surface yesterday has been downlinked to Earth and is currently being analysed by experts.
Researcher pored through more than 10 years of existing Chandra X-ray Observatory data and found stars that repeatedly survive quick, massive surges in space energy. There are no such instances in our galaxy, as stars are destroyed by similar conditions.
Hydrogen. Atomic number 1. It is the simplest and lightest element on the periodic table, but don't be fooled by its humble appearance. With just a single proton and a single electron, it is the most abundant element in the universe and has fueled star formation for the past 13 billion years. Now scientists have mapped the key ingredient's distribution across the Milky Way, revealing details about our galaxy that have never been seen before.
As the search for a hypothetical, unseen planet far, far beyond Neptune's orbit continues, new research provides additional support for the possible existence of such a world and narrows the range of its parameters and location.
Planet Nine the undiscovered planet at the edge of the solar system appears to be responsible for the unusual tilt of the Sun, according to a new study.
Everything we know about the formation of solar systems might be wrong, says two astronomers. They've discovered the first "binary--binary" -- two massive companions around one star in a close binary system, one so-called giant planet and one brown dwarf, or "failed star" The first, called MARVELS-7a, is 12 times the mass of Jupiter, while the second, MARVELS-7b, has 57 times the mass of Jupiter.
After investigating the upper atmosphere of the Red Planet for a full Martian year, NASA's MAVEN mission has determined that the escaping water does not always go gently into space. Hydrogen in Mars' upper atmosphere comes from water vapor in the lower atmosphere. An atmospheric water molecule can be broken apart by sunlight, releasing the two hydrogen atoms from the oxygen atom that they had been bound to. Several processes at work in Mars' upper atmosphere may then act on the hydrogen, leading to its escape.
The Trace Gas Orbiter (TGO) of ESA's ExoMars 2016 has successfully performed the long 139-minute burn required to be captured by Mars and entered an elliptical orbit around the Red Planet, while contact has not yet been confirmed with the mission's test lander from the surface.
Stern said that Pluto's complex, layered atmosphere is hazy and appears to be mostly free of clouds, but the team has spied a handful of potential clouds in images taken with New Horizons' cameras. "If there are clouds, it would mean the weather on Pluto is even more complex than we imagined," Stern said.
After the first direct detection of gravitational waves that was announced last February by the LIGO Scientific Collaboration and made news all over the world, two researchers set out to test whether the observed signal could have been a gravastar or not.
New global images of Mars from the MAVEN mission show the ultraviolet glow from the Martian atmosphere in unprecedented detail, revealing dynamic, previously invisible behavior. They include the first images of "nightglow" that can be used to show how winds circulate at high altitudes.
When the Rosetta spacecraft successfully touched down on comet 67P/Churyumov-Gerasimenko on September 30, 2016, the news was shared globally via Twitter in dozens of languages. Citizens the world over were engaged by the astronomical achievement, and now experts are eager to learn as much as possible about the critically important celestial body of ice.
Next week, ESA's ExoMars has just a single chance to get captured by Mars' gravity. The spacecraft and the mission controllers who will make it so are ready for arrival.
