NASA's IRIS spots nanojets: Shining light on heating the solar corona
In pursuit of understanding why the Sun's atmosphere is so much hotter than the surface, and to help differentiate between a host of theories about what causes this heating, researchers turn to NASA's Interface Region Imaging Spectrograph (IRIS) mission. IRIS was finely tuned with a high-resolution imager to zoom in
'Black dwarf supernova': Physicist calculates when the last supernova ever will happen
"It will be a bit of a sad, lonely, cold place," said theoretical physicist Matt Caplan, who added no one will be around to witness this long farewell happening in the far far future.
Mystery solved: Bright areas on Ceres come from salty water below
Scientists had figured out that the bright areas were deposits made mostly of sodium carbonate -- a compound of sodium, carbon, and oxygen.
NASA's Maven observes Martian night sky pulsing in ultraviolet light
The MAVEN team was surprised to find that the atmosphere pulsed exactly three times per night, and only during Mars' spring and fall.
Early Mars was covered in ice sheets, not flowing rivers, researchers say
To reach this conclusion, lead author Anna Grau Galofre, former PhD student in the department of earth, ocean and atmospheric sciences, developed and used new techniques to examine thousands of Martian valleys. She and her co-authors also compared the Martian valleys to the subglacial channels in the Canadian Arctic Archipelago
New approach refines the Hubble's constant and age of universe
Approaches to date the Big Bang, which gave birth to the universe, rely on mathematics and computational modeling, using distance estimates of the oldest stars, the behavior of galaxies and the rate of the universe's expansion.
The idea is to compute how long it would take all objects to return
Solar Orbiter's first images reveal 'campfires' on the Sun: ESA/NASA mission returns first data, snaps closest pictures of the Sun
According to the scientists behind the mission, seeing phenomena that were not observable in detail before hints at the enormous potential of Solar Orbiter, which has only just finished its early phase of technical verification known as commissioning. "These are only the first images and we can already see interesting
First ever image of a multi-planet system around a sun-like star captured by ESO telescope
Just a few weeks ago, ESO revealed a planetary system being born in a new, stunning VLT image.
NASA astronauts safely splash down after first commercial crew flight to space station
SpaceX's Crew Dragon, carrying Robert Behnken and Douglas Hurley, splashed down under parachutes in the Gulf of Mexico off the coast of Pensacola, Florida at 2:48 p.m.
NASA data helps new model predict big solar flares
As it progresses through its natural 11-year cycle, the Sun transitions from periods of high to low activity, and back to high again.
Surprising number of exoplanets could host life: New insight to inform future NASA missions
This is the conclusion of a study led by UC Riverside astrobiologist Stephen Kane published this week in the Astronomical Journal.
ALMA finds possible sign of neutron star in supernova 1987A
Ever since astronomers witnessed one of the brightest explosions of a star in the night sky, creating Supernova 1987A (SN 1987A), they have been searching for a compact object that should have formed in the leftovers from the blast. Because particles known as neutrinos were detected on Earth on the
Mars 2020 Perseverance Rover Mission to Red Planet successfully launched
Humanity's most sophisticated rover launched with the Ingenuity Mars Helicopter at 7:50 a.m.EDT (4:50 a.m.
Scientists discover volcanoes on Venus are still active: New 3D model provides evidence that Venus is churning inside
"This is the first time we are able to point to specific structures and say 'Look, this is not an ancient volcano but one that is active today, dormant perhaps, but not dead,'" said Laurent Montési, a professor of geology at UMD and co-author of the research paper.
