A new study has shown that optimal global satellite coverage can be achieved with just four satellites, and in a very cost-effective way. The post Scientists Figure Out How to Continuously Watch the Entire Planet With Just 4 Satellites appeared first on Universe Today .
A new image from the ESA’s Mars Express spacecraft shows how beautiful, and desolate, Mars can appear. It also highlights some of the natural process that shape the planet’s surface. The image is of the northern polar region, and it features bright patches of ice, deep dark troughs, and evidence of storms and strong winds.
Astronomers have discovered another candidate exoplanet orbiting our neighbor, Proxima Centauri. A paper announcing these results was just published in the journal Science Advances.
A new study by researchers from the University of Warwick shows how Gamma Ray Bursts can only occur with binary systems. The post It Takes Two Stars to Make a Gamma Ray Burst appeared first on Universe Today .
The Woods Hole Oceanographic Institution (WHOI) says their underwater robot has just completed the first-ever automated underwater sampling operation. The robot is called Nereid Under Ice (NEI) and it collected the sample in Greece. WHOI is developing Nereid in association with NASA’s Planetary Science and Technology from Analog Research (PSTAR) program
LightSail 2 deployed it solar sail five months ago, and it’s still orbiting Earth. It’s a successful demonstration of the potential of solar sail spacecraft. Now the LightSail 2 team at The Planetary Society has released a paper outlining their findings from the mission so far.

The SuperTIGER-2 flight just completed its second tour around Antarctica in its mission to determine the origin and nature of cosmic rays. The post Balloon-Based Cosmic Ray Observatory is Now on its Second Trip Around Antarctica appeared first on Universe Today
Using the SOFIA telescope, a team of NASA astronomers have conducted the most detailed survey of the interior of the Swan Nebula to date. The post New View of the Swan Nebula From NASA’s Airborne SOFIA Telescope appeared first on Universe Today .
20% of the surface of Earth’s Eastern Hemisphere is littered with a certain kind of rock.
A new study led by Princeton researchers has confirmed that in the long run, hot Jupiters are destined to be devoured by their suns. The post In About 3 Million Years, WASP-12b Will Spiral into its Star and be Consumed appeared first on Universe Today
Using data from Hubble and the gravitational lensing technique, a team of astronomers have found definitive evidence that Dark Matter is indeed “cold”. The post Hubble Finds Teeny Tiny Clumps of Dark Matter appeared first on Universe Today .
There’s a new method to measure the expansion rate of the Universe, but it doesn’t resolve the Crisis in Cosmology
In a recent post I wrote about a study that argued dark energy isn’t needed to explain the redshifts of distant supernovae. I also mentioned we shouldn’t rule out dark energy quite yet, because there are several independent measures of cosmic expansion that don’t require supernovae
We tend to think of our Earthly circumstances as normal. A watery, temperate world orbiting a stable yellow star. A place where life has persisted for nearly 4 billion years
Researchers working with data from NASA’s TESS (Transiting Exoplanet Survey Satellite) have a found a planet that orbits two stars.
A new study presented at the 235th meeting of the AAS this week shows how star formation is already happening thanks to the expected collision between the Milky Way and the LMC. The post An Upcoming Impact With the Magellanic Clouds is Already Causing Star Formation in the Milky Way appeared first on Universe Today .
Stars are formed within large clouds of gas and dust known as stellar nurseries. While star formation was once seen as a simple gravitational process, we now know it is a complex dance of interactions. When one star forms it can send shock waves through the interstellar medium that trigger other stars to form.
During its 370 days on the lunar surface, China’s Yutu 2 rover has broken multiple records – including distance traveled and total time spent on the surface. The post Chang’e-4 Wraps Up a Year Roving on the Far Side of the Moon appeared first on Universe Today
NASA’s TESS (Transiting Exoplanet Survey Satellite) has found its first Earth-sized planet located in the habitable zone of its host star. The find was confirmed with the Spitzer Space Telescope. This planet is one of only a few Earth-sized worlds ever found in a habitable zone.
NASA has given us a taste of what the WFIRST will be able to see when it takes to space, previewing what the power of 100 Hubbles will look like. The post This Simulation Shows what We’ll be Able to See with WFIRST appeared first on Universe Today .
