Researchers used supercomputers to create nearly 4 million simulated images depicting the cosmos.
View ArticleMysterious mini-Neptunes
This study discovered mini-Neptunes around four red dwarfs using observations from a global network of ground-based telescopes and the TESS space telescope. These four mini-Neptunes are close to their...
View ArticlePair plasmas found in deep space can now be generated in the lab
Researchers have experimentally generated high-density relativistic electron-positron pair-plasma beams by producing two to three orders of magnitude more pairs than previously reported.
View ArticleHigh-precision measurements challenge our understanding of Cepheids
Scientists have clocked the speed of Cepheid stars -- 'standard candles' that help us measure the size of the universe -- with unprecedented precision, offering exciting new insights about them.
View ArticleInvestigating the origins of the crab nebula
A team of scientists used NASA's James Webb Space Telescope to parse the composition of the Crab Nebula, a supernova remnant located 6,500 light-years away in the constellation Taurus.
View ArticlePair of merging quasars at cosmic dawn
Astronomers have discovered a double-record-breaking pair of quasars. Not only are they the most distant pair of merging quasars ever found, but also the only pair confirmed in the bygone era of the...
View ArticleSatellites to monitor marine debris from space
Detecting marine debris from space is now a reality, according to a new study. Until now, the amount of litter -- mostly plastic -- on the sea surface was rarely high enough to generate a detectable...
View ArticleAstronomers see a massive black hole awaken in real time
In late 2019 the previously unremarkable galaxy SDSS1335+0728 suddenly started shining brighter than ever before. To understand why, astronomers have used data from several space and ground-based...
View ArticleImpacts of space travel on astronauts' eye health
Gravitational changes experienced by astronauts during space travel can cause fluids within the body to shift. This can cause changes to the cardiovascular system, including vessels in and around the...
View ArticleJupiter's great red spot is not the same one Cassini observed in 1600s
Jupiter's iconic Great Red Spot has persisted for at least 190 years and is likely a different spot from the one observed by the astronomer Giovanni Domenico Cassini in 1665, a new study reports. The...
View ArticleSupermassive black hole appears to grow like a baby star
Supermassive black holes pose unanswered questions for astronomers around the world, not least 'How do they grow so big?' Now, an international team of astronomers has discovered a powerful rotating,...
View ArticleIron meteorites hint that our infant solar system was more doughnut than...
Iron meteorites are remnants of the metallic cores of the earliest asteroids in our solar system. Iron meteorites contain refractory metals, such as iridium and platinum, that formed near the sun but...
View ArticleGuiding humanity beyond the moon
What actually happens to the human body in space? While scientists and researchers have heavily researched how various factors impact the human body here on Earth, the amount of information available...
View ArticleStar clusters observed within a galaxy in the early Universe
The history of how stars and galaxies came to be and evolved into the present day remains among the most challenging astrophysical questions to solve yet, but new research brings us closer to...
View ArticleGeologists expect Chang'e-6 lunar surface samples to contain volcanic rock...
On June 25, China's Chang'e-6 (CE-6) lunar probe is set to return to Earth, carrying the first surface samples collected from the farside of the Moon. In anticipation of this historic event, scientists...
View ArticleFirst of its kind detection made in striking new Webb image
For the first time, a phenomenon astronomers have long hoped to directly image has been captured by NASA's James Webb Space Telescope's Near-Infrared Camera (NIRCam). In this stunning image of the...
View ArticleMarsquakes may help reveal whether liquid water exists underground on red planet
If liquid water exists today on Mars, it may be too deep underground to detect with traditional methods used on Earth. But listening to earthquakes that occur on Mars -- or marsquakes -- could offer a...
View ArticleTelltale greenhouse gases could signal alien activity
If aliens modified a planet in their solar system to make it warmer, we'd be able to tell. A new study identifies the artificial greenhouse gases that would be giveaways of a terraformed planet.
