Collisional energy transfer in ethanimine + He system
Announce Type: new Abstract: The ethanimine molecule, CH3CHNH, is one of the prebiotic molecules detected by astronomers in chemically-rich molecular clouds in the Galactic Center. The observations indicate a non-equilibrium distribution of rotational state populations in both the E- and Z-isomers of ethanimine, resulting from the competition between radiative processes and collisions with background gases such as He and H2. Accurate interpretation of these observations requires the use of...
Trouble near the Milky Way: The Large Magellanic Cloud is ripping its smaller neighbor galaxy apart
Trouble near the Milky Way: The Large Magellanic Cloud is ripping its smaller neighbor galaxy apart In the gravitational tug of war between the dwarf galaxy siblings, it's the Small Magellanic Cloud that's losing. The Small Magellanic Cloud seems to be coming undone at the gravitational hands of its sibling galaxy, the Large Magellanic Cloud, which has been found to be unwrapping its little brother's stars. The Small and Large Magellanic Clouds (SMC and LMC for short) are two dwarf irregular...
Wind from Milky Way's supermassive black hole is finally discovered
Wind from Milky Way's supermassive black hole is finally discovered WASHINGTON, June 5 : After five decades of trying, astronomers have finally discovered the wind emanating from the supermassive black hole at the center of our Milky Way galaxy, though it turns out it is more of a gentle breeze than a hurricane. Using data from the Chile-based ALMA telescope and NASA's orbiting Chandra X-ray Observatory, the researchers viewed the cosmic neighborhood around the black hole - called...
Supermassive black holes could be the universe's biggest planet nurseries
May 31, 2026 report Supermassive black holes could be the universe's biggest planet nurseries Paul Arnold Author Lisa Lock Scientific Editor Robert Egan Associate Editor Supermassive black holes are the largest known black holes in the universe, sitting at the center of most large galaxies. They are sometimes described as cosmic monsters because they feed on surrounding gas and dust when they are active, as well as destroy anything that gets too close. But their reputation could be due for a...
Astronomers uncover statistical evidence for recoiling supermassive black holes
Galactic collisions are events of breathtaking proportions. The supermassive black holes (SMBHs) at their centers plunge into a chaotic orbital dance that eventually coalesce into a single remnant. On their way to that point, they could eventually get "kicked" out of the center of their galaxy—and finding these "recoiling" black holes has been a challenge of cosmology for decades.
Distant blazar OP 313 emits very high-energy gamma rays above 100 GeV
June 3, 2026 report Distant blazar OP 313 emits very high-energy gamma rays above 100 GeV Tomasz Nowakowski Author Stephanie Baum Scientific Editor Robert Egan Associate Editor An international team of astronomers have employed one of the Large-Sized Telescopes (LSTs) at the Cherenkov Telescope Array Observatory (CTAO) to observe a distant blazar known as OP 313. Results of the observational campaign, published May 26 on the arXiv preprint server, shed more light on the behavior and nature...
JWST finds a stellar bar in the early universe that breaks all rules
May 31, 2026 report JWST finds a stellar bar in the early universe that breaks all rules Shreejaya Karantha Author Sadie Harley Scientific Editor Robert Egan Associate Editor Astronomers using the James Webb Space Telescope (JWST) have discovered a stellar bar in GN20, a massive galaxy seen just 1.5 billion years after the Big Bang. The new paper was submitted to the preprint server arXiv on May 14. Cosmic funnels Stellar bars are elongated arrangements of stars that cut across the center of...

The American Missile Crisis
Recent global conflicts, from Russia and Ukraine to Iran and Israel, have seen a resurgent awareness of the frailty of US munitions stock, which has been drawn down by both direct and indirect involvement in these events. While exact stockpile volumes are not disclosed, it is estimated that supplies of US warheads and the missiles that carry them have declined by nearly an order of magnitude since their peak during the Cuban Missile Crisis. Analysts have estimated that in the event of a...
China launches debut mission of Falcon 9-like rocket with no advance notice (video)
China launches debut mission of Falcon 9-like rocket with no advance notice (video) A partially reusable Chinese rocket just made a surprise debut. China launched its Long March 12B vehicle for the first time ever on Monday (June 1), sending it up from the Jiuquan Satellite Launch Center in the Gobi Desert. The liftoff occurred without warning: China did not issue airspace closure notices ahead of time, eschewing a safety practice commonly employed by launch operators.
