Sunyaev (IKI) It may well mark a revolution in X-ray astronomy: The eRosita space telescope, which was launched last July, has completed its first complete survey of the sky. Over…
“#New remnant radio galaxy detected” Radio maps of the source J1615 5452 with the synthesized beam shown in the bottom left corner. Credit: Randriamanakoto et al., 2020. Using the Giant Metrewave Radio Telescope (GMRT), astronomers from South Africa and India have discovered a new remnant radio galaxy. The newly detected object, designated J1615 5452 has…
“#Either the heaviest-known neutron star or the lightest-known black hole: LIGO-Virgo finds mystery object in ‘mass gap’” In August of 2019, the LIGO-Virgo gravitational-wave network witnessed the merger of a black hole with 23 times the mass of our sun and a mystery object 2.6 times the mass of the sun. Scientists do not know…
“#CGCS 673 is a semi-regular variable carbon star, study finds” CGCS 673 light curve including ASAS-SN data. Credit: Brincat et al., 2020. Astronomers from Malta and Spain have conducted an observational campaign aimed at investigating the periodic behavior of a carbon star known as CGCS 673. The observations found that the studied object is a…
“#Young giant planet offers clues to formation of exotic worlds” This animation shows a type of gas giant planet known as a hot Jupiter that orbits very close to its star. Finding more of these youthful planets could help astronomers understand how they formed and if they migrate from cooler climes during their lifetimes. Credit:…
“#Astronomers detect teraelectronvolt emission from the gamma-ray burst GRB 190114C” Light curves in the keV, GeV and TeV bands, and spectral evolution in the TeV band for GRB 190114C. Credit: MAGIC Collaboration, 2020. An international team of astronomers has detected a teraelectronvolt (TeV) emission from a gamma-ray burst designated GRB 190114C. The discovery could improve…
“#New research hints at the presence of unconventional galaxies containing two black holes” New research indicates that some galaxies might have two massive black holes at their centers that can emit ultra-powerful jets of energy. Credit: European Space Agency A Clemson University scientist has joined forces with an international team of astronomers to identify periodic…
“#Are planets with oceans common in the galaxy? It’s likely, NASA scientists find” This illustration shows NASA’s Cassini spacecraft flying through plumes on Enceladus in October 2015. Credit: NASA/JPL-Caltech Several years ago, planetary scientist Lynnae Quick began to wonder whether any of the more than 4,000 known exoplanets, or planets beyond our solar system, might…
“#Planets must be formed early, study finds” Artist’s conceptualization of the dusty TYC 8241 2652 system as it might have appeared several years ago when it was emitting large amounts of excess infrared radiation. Credit: Gemini Observatory/AURA artwork by Lynette Cook. https://www.gemini.edu/node/11836 Scientists have found evidence that planets form in a blink of an eye on a…
“#Stunning new Hubble images reveal stars gone haywire” These two new images from the Hubble Space Telescope depict two nearby young planetary nebulae, NGC 6302, dubbed the Butterfly Nebula, and NGC 7027, which resembles a jewel bug. Both are among the dustiest planetary nebulae known and both contain unusually large masses of gas. Credit: NASA,…
