A new article hints at the existence of several black holes in the Hyades cluster -- the closest open cluster to our solar system -- which would make them the closest black holes to Earth ever ...
Using ESO's Very Large Telescope (VLT), astronomers have observed a large dark spot in Neptune's atmosphere, with an unexpected smaller bright spot adjacent to it. This is the first time a dark spot on the planet has ever been observed with a ...
The NASA/ESA Hubble Space Telescope has captured a monster in the making in this observation of the exceptional galaxy cluster eMACS J1353.7+4329, which lies about eight billion light-years from Earth in the constellation Canes Venatici. This ...

A study using data from telescopes on Earth and in the sky resolves a problem plaguing astronomers working in the infrared and could help make better observations of the composition of the universe ...

Astronomers report the first exoplanet jointly discovered through direct imaging and precision astrometry, a new indirect method that identifies a planet by measuring the position of the star it ...

The early universe was a rambunctious place where galaxies often bumped into each other and even merged together. Using NASA's Hubble Space Telescope and other space and ground-based ...

When it comes to measuring how fast the Universe is expanding, the result depends on which side of the Universe you start from. A recent study has calibrated the best cosmic yardsticks to ...

A new study probing the structure and evolution of galaxy clusters shows good agreement with the predictions of standard cosmological ...

Current state-of-the-art instrumentation being sent to Mars to collect and analyze evidence of life might not be sensitive enough to make accurate assessments, according to new ...

Scientists have found how the human brain changes and adapts to weightlessness, after being in space for 6 months. Some of the changes turned out to be lasting -- even after 8 months back on ...

Since their discovery by NASA's Voyager mission in the 1980s, temporary 'spoke' features across Saturn's rings have fascinated scientists, yet eluded explanation. They have been ...

Astronomers have directly measured the mass of a single, isolated white dwarf -- the surviving core of a burned-out, Sun-like star. Researchers found that the white dwarf is 56 percent the mass of ...

In June 2021, NASA's Juno spacecraft flew close to Ganymede, Jupiter's largest moon, observing evidence of magnetic reconnection. A team has used Juno data to examine the electron and ion ...

A new analysis of distant galaxies imaged by NASA's James Webb Space Telescope shows that they are extremely young and share some remarkable similarities to 'green peas,' a rare class ...


ESA's novel Aeolus satellite reliably measures wind speed also in higher air layers and thus in a region of the atmosphere where other direct global wind measurements are relatively sparse. This ...

Astronomers took a 'deep dive' into one of the first images from NASA's James Webb Space Telescope and were rewarded with a surprising discovery: telltale signs of two dozen previously ...

Researchers have discovered web-like plasma structures in the Sun's middle corona. The researchers describe their innovative new observation method, imaging the middled corona in ultraviolet ...

On Dec. 11, 2021, astronomers detected a blast of high-energy light from the outskirts of a galaxy around 1 billion light-years away. The event has rattled scientists' understanding of gamma-ray ...

Peeking out from behind the glare of a bright foreground star, astronomers have uncovered the most extraordinary example yet of a nearby galaxy with characteristics that are more like galaxies in the ...

Following a successful launch of NASA's Space Launch System (SLS), the most powerful rocket in the world, the agency's Orion spacecraft is on its way to the Moon as part of the Artemis ...

It is still a glimpse into the future: Astronauts could be put into artificial hibernation and in this state be better protected from cosmic radiation. At present, there are already promising ...

Three different moments in a far-off supernova explosion were captured in a single snapshot by NASA's Hubble Space Telescope. The star exploded more than 11 billion years ago, when the universe ...
