Scientific ‘red flag’ reveals new clues about our galaxy

Scientific ‘red flag’ reveals new clues about our galaxy Figuring out how much energy permeates the center of the Milky Way—a discovery reported in the July 3 edition of the journal Science Advances—could yield new clues to the fundamental source of our galaxy’s power, said L. Matthew Haffner of Embry-Riddle Aeronautical University. phys.org Go to […]

Take a Flight Over Korolev Crater on Mars

Take a Flight Over Korolev Crater on Mars We love flyover videos from other worlds. These stunning videos, created from imagery gathered by orbiting spacecraft, can give us a sense of what it would be like to fly in an airplane on another planet. This latest flyover video from the European Space Agency’s Mars Express […]

Image: Hubble captures one galaxy, two asteroids

Image: Hubble captures one galaxy, two asteroids At first sight, this image from the NASA/ESA Hubble Space Telescope portrays the sparkling stars of AGC111977, a dwarf galaxy located around 15 million light years away and visible in the lower left part of the image. Other galaxies appear sprinkled across the frame, along with foreground stars […]

It Was Almost Certainly an Asteroid Impact that Wiped Out the Dinosaurs. In Fact, Volcanoes Might Have Helped Life Recover

It Was Almost Certainly an Asteroid Impact that Wiped Out the Dinosaurs. In Fact, Volcanoes Might Have Helped Life Recover It seems almost certain that an asteroid impact wiped out the dinosaurs. But only almost. Another competing theory won’t completely go away: the extinction-by-volcano theory. A new study from the UK piles more evidence on […]

Weekly Space Hangout: July 1, 2020 — Dr. Andrew Siemion, Director of Berkeley SETI Research Center

Weekly Space Hangout: July 1, 2020 — Dr. Andrew Siemion, Director of Berkeley SETI Research Center This week we are pleased to welcome Dr. Andrew Siemion, Director of the Berkeley SETI Research Center, to the WSH. As an astrophysicist, Andrew’s research interests include high energy time-variable celestial phenomena, astronomical instrumentation and the search for extraterrestrial […]

Gaia revolutionises asteroid tracking

Gaia revolutionises asteroid tracking ESA’s Gaia space observatory is an ambitious mission to construct a three-dimensional map of our galaxy by making high-precision measurements of over one billion stars. However, on its journey to map distant suns, Gaia is revolutionising a field much closer to home. By accurately mapping the stars, it is helping researchers […]

Image: Hubble spots feathered spiral

Image: Hubble spots feathered spiral The spiral pattern shown by the galaxy in this image from the NASA/ESA Hubble Space Telescope is striking because of its delicate, feathery nature. These “flocculent” spiral arms indicate that the recent history of star formation of the galaxy, known as NGC 2775, has been relatively quiet. There is virtually […]

Astronomers observe nova V659 Sct during outburst

Astronomers observe nova V659 Sct during outburst Using the TIGRE telescope, astronomers have conducted spectroscopic observations of recently discovered nova known as V659 Sct during multiple phases of its outburst. Results of this observational campaign, presented in a paper published June 24 on the arXiv pre-print server, shed more light on the properties of this […]

Complete and Total Mayhem in a Distant Galaxy Collision

Complete and Total Mayhem in a Distant Galaxy Collision A cluster of galaxies is nothing trivial. The shocks, the turbulence, the energy, as all of that matter and energy merges and interacts. And we can watch all the chaos and mayhem as it happens. A team of astronomers are looking at the galaxy cluster Abell […]

A binary star as a cosmic particle accelerator

A binary star as a cosmic particle accelerator With a specialized telescope in Namibia a DESY-led team of researchers has proven a certain type of binary star as a new kind of source for very high-energy cosmic gamma-radiation. Eta Carinae is located 7500 lightyears away in the constellation Carina (the ship’s keel) in the Southern […]

Astronomers see unexpected molecule in exoplanet atmosphere

Astronomers see unexpected molecule in exoplanet atmosphere SRON-astronomers have found the signature for aluminum oxide (AlO) in the spectrum of exoplanet WASP-43b. This came as a surprise because AlO is expected to stay hidden in the lower atmospheric layers. It is only the second time that astronomers have observed the molecule in an exoplanet’s atmosphere. […]
