Early Mars was covered in ice sheets, not flowing rivers, researchers sayA large number of the valley networks scarring Mars's surface were carved by water melting beneath glacial ice, not by free-flowing rivers as previously thought, according to new research. The findings effectively throw cold water on the dominant 'warm and wet ancient Mars' hypothesis, which postulates that rivers, rainfall and oceans once existed on the red planet.NASA astronauts safely splash down after first commercial crew flight to space stationTwo NASA astronauts splashed down safely in the Gulf of Mexico Sunday for the first time in a commercially built and operated American crew spacecraft, returning from the International Space Station to complete a test flight that marks a new era in human spaceflight.Cooling of Earth caused by eruptions, not meteorsAncient sediment found in a central Texas cave appears to solve the mystery of why the Earth cooled suddenly about 13,000 years ago.NASA data helps new model predict big solar flaresScientists have developed a new model that successfully predicted seven of the Sun's biggest flares from the last solar cycle, out of a set of nine. With more development, the model could be used to one day inform forecasts of these intense bursts of solar radiation.'Little brain' or cerebellum not so little after allWhen we say someone has a quick mind, it may be in part thanks to our expanded cerebellum that distinguishes human brains from those of macaque monkeys, for example. High-resolution imaging shows the cerebellum is 80 percent of the area of the cortex, indicating it has grown as human behavior and cognition evolved.Mars 2020 Perseverance Rover Mission to Red Planet successfully launchedNASA's Mars 2020 Perseverance rover mission is on its way to the Red Planet to search for signs of ancient life and collect samples to send back to Earth.Study sheds light on the evolution of the earliest dinosaursGeological evidence suggests the known dinosaur groups diverged early on, supporting the traditional dinosaur family tree.New blood test shows great promise in the diagnosis of Alzheimer's diseaseA new blood test demonstrated remarkable promise in discriminating between persons with and without Alzheimer's disease and in persons at known genetic risk may be able to detect the disease as early as 20 years before the onset of cognitive impairment, according to a large international study.

How Loop Quantum Gravity Could Match Anomalies in the CMB with Large Structures in the Modern Universe
A strange celestial tension could be caused by a cosmic tango between events at very small and very large scales.

On July 5, 2016, NASA’s Juno spacecraft arrived around Jupiter, becoming the second mission in history to study the gas giant from orbit – the last being the Galileo spacecraft, which orbited Jupiter from 1995 to 2003. Since then, the spacecraft has gathered data on Jupiter’s atmosphere, composition, gravity field, and magnetic field in the …

Comets visit the inner Solar System, and leave without saying goodbye. Maybe they leave a trail of dust behind, and when the Earth passes through it, we get a pretty light show in the night sky, in the form of a meteor shower. Likewise, asteroids frequently go whizzing by, though they don’t leave us with …

There’s always more than one way to look at the world. There’s also more than one way to look at a galaxy. And sometimes combining those ways of looking can result in something truly special. That is what happened recently when a team of astronomers from seven different universities in four different countries used three …

Quasars are the most powerful sources of light in the universe, but sometimes they’re hard to find. A team of astronomers used the Chandra X-ray Space Telescope to find some diamonds in the rough. When gas finds itself in the center of a galaxy, it must come toe-to-toe with a truly terrible monster: a supermassive …

Coronavirus measures for hosted meetings and visitorsCryoSat taken to new heights for ice science
Ice plays a critical role in keeping Earth’s climate cool, but our rapidly warming world is taking its toll and ice is in general decline. For more than 10 years, ESA’s CryoSat has been returning critical information on how the height of our fragile ice fields is changing. Nevertheless, to gain even better insight, ESA has spent the last two weeks nudging CryoSat into a higher orbit to synchronise it with NASA’s ICESat-2 so that scientists can benefit from simultaneous measurements from different space sensors.Meet the Experts: Satellite NavigationVideo: 00:06:21
