ESA’s first Earth observation satellite was launched on 23 November 1977. When the first Meteosat satellite took its place in the sky, it completed coverage of the whole globe from geostationary orbit and laid the foundations for European and world cooperation in meteorology that continues today.
Researchers have hypothesized that the universe contains "dark matter." They have also posited the existence of "dark energy." These two hypotheses account for the movement of stars in galaxies and for the accelerating expansion of the universe. But according to...
Space research. What's it ever done for me? Well, quite a bit as it turns out...
The remains of a blazing meteorite that lit up the dark skies of the Arctic last week are believed scattered near a lake in northern Finland, amateur Finnish astronomers said Wednesday.
When comet 45P zipped past Earth early in 2017, researchers observing from NASA's Infrared Telescope Facility, or IRTF, in Hawai'i gave the long-time trekker a thorough astronomical checkup. The results help fill in crucial details about ices in Jupiter-family comets and reveal that quirky 45P doesn't quite match any comet studied so far.
(Phys.org)—Chilean researchers have presented a chemical study of the old, metal-rich globular cluster NGC 5927. The new research determines abundances of 22 elements in seven giant stars of the cluster. The findings are available in a paper published November 8 on the arXiv pre-print repository.
Using the Subaru Telescope atop Maunakea, researchers have identified 11 dwarf galaxies and two star-containing halos in the outer region of a large spiral galaxy 25 million light-years away from Earth. The findings, published in The Astrophysical Journal, provide new insight into how these 'tidal stellar streams' form around galaxies.

For the first time ever, astronomers have studied a 400-meter-long "monolith-like" asteroid that has entered the Solar System from interstellar space. Observations from ESO’s Very Large Telescope in Chile and other observatories around the world show that this unique object...
"We've shown that the heaviest elements in the periodic table, whose origin was shrouded in mystery until today are made in the mergers of neutron stars,” said Edo Berger with the Harvard-Smithsonian Center for Astrophysics. "Each merger can produce more...
Astronomers offer new details about Oumuamua, a probable asteroid arriving from beyond the solar system and leaving in a big hurry.
Astronauts at the International Space Station will feast Thursday on pouches of Thanksgiving turkey.
It came from outer space … and went back there two weeks later, having astonished and excited astronomers and planetary scientists. A cigar-shaped object, less than half a kilometre long and barely bright enough to be detected by the world's most powerful telescopes, paid us a flying visit in October this year – reminding us that the heavens still hold plenty of surprises.
Ever wonder what would happen if you got sick in space? NASA has sent bacteria samples into low-Earth orbit to help find out.
A rover crawls over rocky terrain on Spain's Canary Island of Lanzarote, also known as the island of a thousand volcanoes. A drone follows it closely from the sky as the Sun sets.
How good is your Martian geography? Does Valles Marineris ring a bell? This area is known for having landslides that are among the largest and longest in the entire solar system. They make the perfect object of study due to their steep collapse close to the scarp, extreme thinning, and long front runout. Show More Summary
A University of Texas research team found that one of the great mysteries of the lunar body's formation - how it could develop a crust composed of just one mineral - cannot be explained by the initial crust formation and...
More than a century ago, American writer Mark Twain observed a curious phenomenon at ancient Mono Lake, just to the east of Yosemite National Park: enormous numbers of small flies would crawl underwater to forage and lay eggs, but each...
(University of Turku) Neutron stars are made out of cold ultra-dense matter. How this matter behaves is one of the biggest mysteries in modern nuclear physics. Researchers developed a new method for measuring the radius of neutron stars which helps them to understand what happens to the matter inside the star under extreme pressure.
(Penn State) For the first time, a science experiment has measured Earth's ability to absorb neutrinos -- the smaller-than-an-atom particles that zoom throughout space and through us by the trillions every second at nearly the speed of light. Show More Summary
