The planet's auroras are known to produce low-energy X-ray light. A new study finally reveals higher-frequency X-rays and explains why they eluded another mission 30 years ago.
Scientists have been studying Jupiter up close since the 1970s, but the gas giant is still full of mysteries. New observations by NASA's NuSTAR space observatory have revealed the highest-energy light ever detected Early findings from HERA telescope promise deeper understanding of the cosmic dawn

All through history, humans have created and shared stories that ponder the creation of stars - what they are and how the first stars came to be. Now, with new results from the Hydrogen Epoch of Reionization Array (HERA), a radio telescope located at the South Africa Karoo Astronomy Reserve, MIT scientists are one small, but significant, step closer to understanding that history.

Scientists have produced the largest and most accurate virtual representation of the Universe to date. An international team of researchers, led by the University of Helsinki, and including members from Durham University in the UK, used supercomputer simulations to recreate the entire evolution of the cosmos, from the Big Bang to the present. The findings are published in the Monthly Notices of New planet detected around star closest to the Sun

A team of astronomers using the European Southern Observatory's Very Large Telescope (ESO's VLT) in Chile have found evidence of another planet orbiting Proxima Centauri, the closest star to our Solar System. This candidate planet is the third detected in the system and the lightest yet discovered orbiting this star. At just a quarter of Earth's mass, the planet is also one of the lightest exopl Planetary bodies observed in habitable zone of dead star

A ring of planetary debris studded with moon-sized structures has been observed orbiting close to a white dwarf star, hinting at a nearby planet in the "habitable zone" where water and thus life could exist, according to a new study led by UCL researchers. The research is published in Monthly Notices of the Royal Astronomical Society.

Researchers from the University of Jena and the Max Planck Institute for Astronomy have demonstrated an unusual new form of chemical reaction that could allow some of the smallest biomolecules, namely peptides, to form on the icy surface of dust grains in outer space.
Peptides are one of the basic building blocks of life, and the new discovery bolsters scenarios in which complex organic mo New detection method for quasars in the early Universe

Astronomers from Leiden Observatory have developed a new method to find distant quasars and better distinguish them from other objects that look like them, using machine learning techniques. The research result has been accepted for publication in the journal Astronomy and Astrophysics.

Webb telescope spots its first star—and takes a selfie

Star light, star bright, the James Webb Space Telescope has seen its first star (though it wasn't quite tonight)—and even taken a selfie, NASA announced Friday.
The steps are part of the months-long process of aligning the observatory's enormous golden mirror that astronomers hope will begin unraveling the mysteries of the early Universe by this summer.
The first picture sent back of the cosmos is far from stunning: 18 blurry white dots on a black background, all showing the same object: HD 84406 a bright, isolated star in the constellation Ursa Major.

The James Webb Space Telescope is nearing completion of the first phase of the months-long process of aligning the observatory’s primary mirror using the Near Infrared Camera (NIRCam) instrument.
ESA's Vega rocket marks ten years with countdown to more powerful successor
Friday, 11 February 2022 14:14 Write a comment
Ten years ago today, ESA opened a new era of independent access to space with the inaugural flight of its small launcher Vega. Flying from Europe's Spaceport in French Guiana, Vega has gone on to earn a reputation for precision and versatility in anticipation of a more capable version, Vega-C.
Placing medium-sized satellites into the low Earth polar orbits that are ideal for scientific and Earth observation missions—about 1430 kg to 700 km—is Vega's trademark capability. But the vehicle has also delivered an ESA science mission to deep space—the gravitational wave detector demonstration mission, LISA Pathfinder—and followed the equatorial flight path needed for an experimental IXV "lifting body" payload that paved the way for a European launchpad-to-runway space transportation service, with ESA's uncrewed Space Rider vehicle.
Snow-washed Greece

Rare snowfall over Greece may be the new normal.
For the second year in a row, Greece experienced unprecedented amounts of snow, blanketing the country in white. ESA astronaut Matthias Maurer took this bird’s eye view of the town of Chalcis, along the Euboean Gulf, from the International Space Station in early February.
He posted to social media, noting, “In keeping with its national colours, wintry Greece presented itself in blue and white.”
Storm Elpida swept across Greece and also parts of Turkey, causing mass disruption to the Mediterranean country known more for white-sand beaches and whitewashed homes than snow.
