Forty years of Meteosat

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.

"It Appears that Dark Energy May Not Actually Exist" --A New Assault on the Very Existence of this Unknown Phenomena

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...

Finns want to look for remains of Arctic meteorite (Update)

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.

NASA telescope studies quirky comet 45P

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.

Researchers conduct chemical study of an old, metal-rich globular cluster

(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.

Uncovering the origins of galaxies' halos

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.

ESO/NASA Video --Alien Interstellar Object "Unlike Anything We've Ever Seen" (WATCH Today's 'Galaxy' Stream)

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...        

The LIGO Spacetime Event --"First Giant Galaxy We Observed had a New Source of Light Popping Right Out at Us" (WATCH Video)

"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...        

Out There: An Interstellar Visitor Both Familiar and Alien

Astronomers offer new details about Oumuamua, a probable asteroid arriving from beyond the solar system and leaving in a big hurry.

Lofty Thanksgiving: Astronauts feasting on pouches of turkey

Astronauts at the International Space Station will feast Thursday on pouches of Thanksgiving turkey.

Discovery of cigar-shaped asteroid from outer space could help unveil secrets of extrasolar worlds

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.

NASA is sending E. coli to space for astronaut health

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.

Ice shapes the landslide landscape on Mars

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

Lunar Scientists Solve One of the Great Mysteries of the Moon's Formation

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...        

Caltech Scientists Solve a Mystery --"The Strange Case of the Mono Lake Scuba-Diving Fly" (WATCH Video)

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...        

New method to measure neutron star size uses modeling based on thermonuclear explosions

(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.

IceCube experiment finds Earth can block high-energy particles from nuclear reactions

(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
