ESA and NASA satellites deliver first joint picture of Greenland Ice Sheet...
Scientists have delivered the first measurements of Greenland Ice Sheet thickness change using data from ESA and NASA ice satellite missions. With global warming causing the Greenland Ice Sheet to melt...
View ArticleDark energy 'doesn't exist' so can't be pushing 'lumpy' Universe apart
One of the biggest mysteries in science -- dark energy -- doesn't actually exist, according to researchers looking to solve the riddle of how the Universe is expanding. For the past 100 years,...
View ArticleMysteries of icy ocean worlds
A study introduces a novel thermodynamic concept called the 'centotectic' and investigates the stability of liquids in extreme conditions -- critical information for determining the habitability of icy...
View ArticleScientists pin down the origins of a fast radio burst
Astronomers pinned down the origins of at least one fast radio burst, a brief and brilliant explosion of radio waves emitted by an extremely compact object. The team's novel technique might also reveal...
View ArticleThe carbon in our bodies probably left the galaxy and came back on cosmic...
Scientists recently discovered that the giant 'conveyer belt' currents that push star-forged material out of our galaxy and pull it back in can also transport carbon atoms. That means that a good deal...
View ArticleResearch may boost next-generation space rockets
Hidden patterns in electric propulsion plasma beams could help ensure the success of long-term space missions.
View ArticleCitizen science reveals that Jupiter's colorful clouds are not made of...
Collaborative work by amateur and professional astronomers has helped to resolve a long-standing misunderstanding about the composition of Jupiter's clouds. Instead of being formed of ammonia ice --...
View ArticleBeyond the 'Dragon Arc', a treasure trove of unseen stars
Taking advantage of a cosmic 'double lens,' astronomers resolved more than 40 individual stars in a galaxy so far away its light dates back to when the universe was only half its present age.
View ArticlePluto-Charon formation scenario mimics Earth-Moon system
A researcher has used advanced models that indicate that the formation of Pluto and Charon may parallel that of the Earth-Moon system. Both systems include a moon that is a large fraction of the size...
View ArticleNew data on atmosphere from Earth to the edge of space
Researchers have created a dataset of the whole atmosphere, enabling new research to be conducted on previously difficult-to-study regions. Using a new data-assimilation system called JAGUAR-DAS, which...
View Article'What is that?' Scientists explain white patch that appears near northern lights
A whitish, grey patch that sometimes appears in the night sky alongside the northern lights has now been explained.
View ArticleA Sustainable Development Goal for space?
An international team of scientists has called for the creation of an 18th addition to the United Nations Sustainable Development Goals, which would aim to mitigate against the accumulation of space...
View ArticleLight, flexible and radiation-resistant: Organic solar cells for space
Radiation testing suggests that solar cells made from carbon-based, or organic, materials could outperform conventional silicon and gallium arsenide for generating electricity in the final frontier, a...
View ArticleX-ray flashes from a nearby supermassive black hole accelerate mysteriously
Astronomers observed flashes of X-rays coming from a supermassive black hole at a steadily increasing clip. The source could be the core of a dead star that's teetering at the black hole's edge.
View ArticleNew study unveils breakthrough in understanding cosmic particle accelerators
Scientists have come a step closer to understanding how collisionless shock waves -- found throughout the universe -- are able to accelerate particles to extreme speeds.
View ArticleNASA's Hubble tracks down a 'blue lurker' among stars
The name 'blue lurker' might sound like a villainous character from a superhero movie. But it is a rare class of star that NASA's Hubble Space Telescope explored by looking deeply into the open star...
View ArticleHubble reveals surprising spiral shape of galaxy hosting young jet
The night sky has always played a crucial role in navigation, from early ocean crossings to modern GPS. Besides stars, the United States Navy uses quasars as beacons. Quasars are distant galaxies with...
View ArticleThree tiny 'stellar-ghost-town' galaxies discovered
By combining data from the DESI Legacy Imaging Surveys and the Gemini South telescope, astronomers have investigated three ultra-faint dwarf galaxies that reside in a region of space isolated from the...
View ArticleNot all Hot Jupiters orbit solo
Hot Jupiters are giant planets initially known to orbit alone close to their star. During their migration towards their star, these planets were thought to accrete or eject any other planets present....
View ArticleSuper-Earth vs. Sub-Neptune? The winner is Super-Venus!
New observational data and simulation models have confirmed a new type of planet unlike anything found in the Solar System. This provides another piece of the puzzle to understand how planets and...
