Gamma-ray bursts are generally thought to come in two flavors — supernovae or neutron star mergers. But discoveries are blurring that line.

Bizarre long gamma-ray burst came from merging stellar corpses
Scientists have tracked a high-energy blast of radiation back to the collision of two neutron stars and the kilonova explosion that resulted from the violent merger.
MTG-I1 never to be seen again
As preparations to launch Europe’s first Meteosat Third Generation Imager satellite continue, the team at Europe’s Spaceport in Kourou, French Guiana, has bid farewell to their precious satellite as it was sealed from view within the Ariane 5 rocket’s fairing. This all-new weather satellite is set to take to the skies on 13 December.
The 1st photograph of all Earth: 50 years on, Blue Marble still inspires
The astronauts of NASA's Apollo 17 spacecraft, the last crewed mission to the moon, took a photograph of Earth and changed the way we visualized our planet forever.
Watch the Cold Moon rise tonight (Dec. 7), the last full moon of 2022
On Wednesday (Dec. 7) the moon will reach its full moon phase as December's aptly named Cold Moon, the final full moon of 2022, rises for most of the night.
Launches secured for five Sentinel satellites
A contract signed today between ESA and Arianespace has ensured rides into orbit for five Copernicus Sentinels: Sentinel-1D, Sentinel-2C, Sentinel-3C, and the Copernicus Anthropogenic Carbon Dioxide-A and -B satellites. All the satellites will be launched on Vega-C rockets from Europe’s Spaceport in French Guiana and are scheduled to take place between 2024 and 2026.
Gamma-rays may have helped meteorites seed Earth with the building blocks of life
New research solves the puzzle of how amino acids formed within space rocks that bombarded Earth during the violent early epoch of the solar system.
Apollo 17 in Pictures: “God Willing, as We Shall Return”
On the 50th anniversary of Apollo 17, we look back at iconic photos as well as rarely seen images from the mission.
China's Shenzhou 14 astronauts begin recovery on Earth after 6-month mission (video)
Three astronauts who helped finish the construction of China's Tiangong space station are back in Beijing to start the recovery process after spending half a year in orbit.
Happy anniversary, Apollo 17! Final moonwalking mission launched 50 years ago today
NASA's Apollo 17 mission lifted off on Dec. 7, 1972, sending Gene Cernan, Harrison Schmitt and Ronald Evans toward Earth's nearest neighbor.
SpaceX reveals 'Starshield' satellite project for national security use
SpaceX just revealed a new project called Starshield, which will leverage the company's Starlink satellite-internet tech for government customers.
Will We Ever Go Back to Explore the Ice Giants? Yes, If We Keep the Missions Simple and Affordable
It’s been over 35 years since a spacecraft visited Uranus and Neptune. That was Voyager 2, and it only did flybys. Will we ever go back? There are discoveries waiting to be made on these fascinating ice giants and their moons.
Amazon tests machine learning software to analyze satellite images from space
For the past 10 months, Amazon has been testing a machine learning software in space that can analyze Earth observation images on its own and send only the best ones to Earth.
A new Hubble Image Reveals a Shredded Star in a Nearby Galaxy
The Hubble Space Telescope, to which we owe our current estimates for the age of the universe and the first detection of organic matter on an exoplanet, is very much doing science and still alive. It’s latest masterpiece remixes an old hit – apparently a growing trend in science as well as music.
Listen to the Artemis 1 Orion capsule phone home from deep space
Orion broadcasts its data signal toward Earth, where it is received by three dishes that make up NASA's Deep Space Network, but amateur observers can also tune in throughout the mission.
Evidence of a Megatsunami on Mars
Things were pretty wet back on Mars about three and a half billion years ago. You wouldn’t know that by looking at the planet today. But, would you believe a megatsunami happened there? It turns out that not one, but two of these rogue waves happened there some 3.4 billion years ago.
What time will the moon eclipse Mars on Dec. 7?
A bright Mars at opposition will disappear behind the moon on Wednesday (Dec. 7), but exactly when you should look up depends on where you are.
Solar cycle peak reduces cosmic rays around Mars, Venus and Earth
Measurements taken at Earth's neighbors, Mars and Venus, show the battle between high-energy cosmic rays from beyond the solar system and the influence of the sun in the inner solar system.
Mauna Loa's continuing eruption is spectacular in satellite views
Satellites keep watching as the Mauna Loa volcano on Hawaii's Big Island continues spewing geysers of boiling lava and plumes of volcanic ash over a week after it woke up from a 38-year sleep.
NASA's revolutionary Moonboard launched Artemis 1 coverage to new heights
NASA's media team incorporated an advanced 'Moonboard' touchscreen to help viewers understand the launch of the SLS rocket and Orion's journey around the moon.
Not Just Stars. Gaia Mapped a Diverse and Shifting Universe of Variable Objects
We’ve reported on Gaia’s incredible data-collection abilities in the past. Recently, it released DR3, its latest data set, with over 1.8 billion objects in it. That’s a lot of data to sift through, and one of the most effective ways to do so is through machine learning. A group of researchers did just that by using a supervised learning algorithm to classify a particular type of object found in the data set. The result is one of the world’s most comprehensive catalogs of the type of astronomical object known as variables.
