Optical telescopes obtain long-term monitoring results of flux variability in blazars Blazars are a special kind of rare active galactic nuclei. They are currently the most likely candidates for high-energy neutrinos. Their relativistic jets may be the origin area of super-high-energy cosmic rays and neutrinos. phys.org Go to Source
Scientists reveal photochemical rationale of SH(X)/H2S abundance ratios in interstellar medium Research group led by Prof. YUAN Kaijun and Prof. YANG Xueming from the Dalian Institue of Chemical Physics (DICP) of the Chinese Academy of Sciences revealed the photochemical rationale of SH(X)/H2S abundance ratios in interstellar medium with the help of Dalian Coherent Light Source.

Warped space-time to help WFIRST find exoplanets NASA’s Wide Field Infrared Survey Telescope (WFIRST) will search for planets outside our solar system toward the center of our Milky Way galaxy, where most stars are. Studying the properties of exoplanet worlds will help us understand what planetary systems throughout the galaxy are like and how planets […]
Weekly Space Hangout: April 1, 2020 – Dr. Robert B. Hayes and Radiation Shielding in Space Hosts: Fraser Cain (universetoday.com / @fcain) Dr. Kimberly Cartier (KimberlyCartier.org / @AstroKimCartier ) Pam Hoffman (EverydaySpacer.com / @EverydaySpacer) Michael Rodruck (@michaelrodruck) Announcements: This week we are airing Fraser’s prerecorded interview with Dr. Robert B. Hayes, Associate Professor of Nuclear Engineering at North […]
Study determines burst properties of the most recurring transient magnetar Using NASA’s Fermi and Swift spacecraft, astronomers have investigated SGR J1935+2154, the most recurring transient magnetar known to date. The new research sheds more light on the burst properties of this object. The study is detailed in a paper published March 23 on the arXiv […]
NASA selects mission to study causes of giant solar particle storms NASA has selected a new mission to study how the Sun generates and releases giant space weather storms—known as solar particle storms—into planetary space. Not only will such information improve understanding of how our solar system works, but it ultimately can help protect astronauts […]
Unravelling the mystery of black holes: Scientists release stellar code to the public Today, team COMPAS (Compact Object Mergers: Population Astrophysics and Statistics) has announced the first public beta release of their rapid binary population synthesis code (available for download here). phys.org Go to Source
How were Supermassive Black Holes Already Forming and Releasing Powerful Jets Shortly After the Big Bang? A series of studies has shown that the seeds of supermassive black holes and relativistic jets existed much sooner than expected The post How were Supermassive Black Holes Already Forming and Releasing Powerful Jets Shortly After the Big Bang?

Image: Hubble hooks a one-arm galaxy NGC 4618 was discovered on April 9, 1787, by the German-British astronomer William Herschel, who also discovered Uranus in 1781. Only a year before discovering NGC 4618, Herschel theorized that the “foggy” objects astronomers were seeing in the night sky were likely to be large star clusters located much […]
Are the Gaps in These Disks Caused by Planets? Astronomers like observing distant young stars as they form. Stars are born out of a molecular cloud, and once enough of the matter in that cloud clumps together, fusion ignites and a star begins its life. The leftover material from the formation of the star is […]
How Will Clouds Obscure the View of Exoplanet Surfaces? A new study shows how the presence of a cloud layer could make it harder for the James Webb Space Telescope to detect water on exoplanets. The post How Will Clouds Obscure the View of Exoplanet Surfaces? appeared first on Universe Today. Universe Today Go to […]
The heliosphere looks a lot weirder than we originally thought Every second of every day, our sun spits out a stream of tiny high-energy particles, known as the solar wind. This wind blows throughout the solar system, extending far beyond the orbits of the planets and out into interstellar space. But the farther from the […]
ALMA resolves gas impacted by young jets from supermassive black hole Astronomers obtained the first resolved image of disturbed gaseous clouds in a galaxy 11 billion light-years away by using the Atacama Large Millimeter/submillimeter Array (ALMA). The team found that the disruption is caused by young powerful jets ejected from a supermassive black hole residing […]
Highest Resolution Mosaic Image of the Surface of Bennu NASA and the University of Arizona have released a stunning new global map of asteroid Bennu. At 2 inches (5 cm) per pixel, this is the highest-resolution global map of any planetary body. This hi-res map will help guide the OSIRIS-REx spacecraft to the surface of […]

This Powerful Ion Engine Will Be Flying on NASA’s DART Mission to Try and Redirect an Asteroid Despite humanity’s current struggle against the novel coronavirus, and despite it taking up most of our attention, other threats still exist. The very real threat of a possible asteroid strike on Earth in the future is taking a […]
Following Comet Y1 ATLAS: the ‘Lost Comet’ of Spring Got clear skies? If you’re like us, you’ve been putting the recent pandemic-induced exile to productive use, and got out under the nighttime sky. And though 2020 has yet to offer up a good bright ‘Comet of the Century’ to keep us entertained, there have been […]
Supernova remnant W49B investigated with XMM-Newton Chinese astronomers using ESA’s XMM-Newton spacecraft have investigated a luminous supernova remnant (SNR) known as W49B. Results of the new study, presented in a paper published March 16 on arXiv.org, shed more light on the properties of this SNR and on the nature of its progenitor. phys.org Go to […]
