X-rays from a nuclear explosion could redirect an asteroid
Scientists have found nuclear weapons could actually help deflect an incoming cosmic impact — not by blowing an asteroid up, but by showering it with X-ray radiation.
NASA’s Perseverance Mars rover is enroute to conduct 1st crater rim study at 'Dox Castle'
NASA's Perseverance Mars rover will soon arrive at its first stop during its arduous trek to the western edge of Jezero Crater.

Soyuz brings two cosmonauts, NASA astronaut back to Earth after record-setting mission
The Soyuz MS-25/71S spacecraft carrying commander Oleg Kononenko, Nikolai Chub and NASA astronaut Tracy Dyson undocked from the International Space Station early Monday as the two spacecraft were passing 260 miles above eastern Mongolia. Image: NASA
Cosmonaut Oleg Kononenko, now the world’s most experienced spaceman, first-time flier Nikolai Chub and NASA veteran Tracy Dyson undocked from the International Space Station and returned to Earth Monday, closing out a record-setting mission with a picture-perfect landing in Kazakhstan.
Those Aren't Dyson Spheres, They're HotDOGs
If there really are advanced alien civilizations out there, you’d think they’d be easy to find. A truly powerful alien race would stride like gods among the cosmos, creating star-sized or galaxy-sized feats of engineering. So rather than analyzing exoplanet spectra or listening for faint radio messages, why not look for the remnants of celestial builds, something too large and unusual to occur naturally?
How dark energy could relieve 'Hubble tension' and galaxy headaches
The Hubble tension, a longstanding problem in cosmology, could potentially be relieved if early dark energy is taken into account.
A New Catalog Charts the Evolution of the Universe Over Time
An atlas doesn’t seem to be an essential item in cars these days but think about them and most people will think about distances. An atlas of the stars not only covers distances but must also take into account time too. The Andromeda galaxy for example is so far away that its light takes 2.5 million years to reach us. A team of researchers have now built a catalogue that contains information on millions of galaxies including their distance and looks back in time up to 10 billion years!
The largest Einstein Cross ever discovered dwells among a rare 'carousel' of galaxies
The largest Einstein Cross dwells among a rare arrangement of seven gravitationally lensed galaxies called the Carousel Lens located between 7 billion and 12 billion light-years from Earth.
Soyuz MS-25 lands from ISS with NASA astronaut and record-setting cosmonauts (video)
Three crewmates have landed Earth after a record-long stay on the International Space Station (ISS) for two of them. For one, the 374 days has amounted to only a third of his total time in space.
Astronomers catalog over 500 extremely powerful cosmic explosions
Astronomers have cataloged over 500 gamma-ray bursts, which are some of the most violent explosions in the cosmos.
Did a Ring of Rocks and Dust Orbit Earth Before the Dinosaurs Roamed?
A team of scientists thinks a clustering of ancient impact craters points to a temporary ring around Earth hundreds of millions of years ago.
Hera planetary defence mission: solving asteroid mysteries
Video: 00:03:12
There’s a mystery out there in deep space – and solving it will make Earth safer. That’s why the European Space Agency’s Hera mission is taking shape – to go where one particular spacecraft has gone before.
Sentinel-1B journeys back to Earth
The Sentinel-1B satellite, the second satellite of the Copernicus Sentinel-1 mission, completed its disposal process – which included lowering its orbit and passivating its systems to ensure re-entry into Earth’s atmosphere within 25 years.
This Might Be the Best Gravitational Lens Ever Found
A gravitational lens is the ultimate funhouse mirror of the Universe. It distorts the view of objects behind them but also supplies amazing information about distant galaxies and quasars. Astronomers using Hubble Space Telescope (HST) recently released a new image of one of these weird apparitions called “The Carousel Lens”. It’s a rare alignment of seven background galaxies that all appear distorted by an intervening galaxy cluster.
High-Resolution Images of the Sun Show How Flares Impact the Solar Atmosphere
Solar flares are a fascinating thing and have a profound effect on what astronomers refer to as “space weather.” These events vary with the Sun’s 11-year solar cycle, releasing immense amounts of radiation across the electromagnetic spectrum (from extreme ultraviolet to X-rays) into space. The effects of flares have been observed since time immemorial, which include aurorae at high latitudes (Aurora Borealis and Australis), but have only been the subject of study and prediction for about a century and a half. Still, there is much that remains unknown about these dramatic events.
