In a First, Scientists Map Particle-Laden Rivers in the Sky
Wednesday, 05 May 2021 07:17Last summer, "Godzilla" came for the Caribbean and the U.S. Gulf Coast. This particular monster wasn't of the sci-fi variety, but a massive dust storm kicked up by winds from the Sahara Desert and carried an ocean away. The dust storm was an extreme example of a phenomenon that happens regularly: the global transport of dust, soot, and other airborne particles collectively known as aerosols by j
uGMRT reveals for the first time the patchy environment of a rare cosmic explosion
Wednesday, 05 May 2021 07:17Scientists from the National Centre for radio Astrophysics of the Tata Institute of Fundamental Research (NCRA-TIFR) Pune used the upgraded Giant Metrewave Radio Telescope (uGMRT) to determine that AT 2018 cow, the first of a newly discovered class of cosmic explosions, has an extremely patchy environment. Sources like AT 2018cow release an enormous amount of energy, nonetheless fade extremely r
Hubble Watches How a Giant Planet Grows
Wednesday, 05 May 2021 07:17NASA's Hubble Space Telescope is giving astronomers a rare look at a Jupiter-sized, still-forming planet that is feeding off material surrounding a young star. "We just don't know very much about how giant planets grow," said Brendan Bowler of the University of Texas at Austin. "This planetary system gives us the first opportunity to witness material falling onto a planet. Our results open
Small galaxies likely played important role in evolution of the Universe
Wednesday, 05 May 2021 07:17A new study led by University of Minnesota astrophysicists shows that high-energy light from small galaxies may have played a key role in the early evolution of the Universe. The research gives insight into how the Universe became reionized, a problem that astronomers have been trying to solve for years. The research is published in The Astrophysical Journal, a peer-reviewed scientific jou
Are there anti-stars around us
Wednesday, 05 May 2021 07:17What if some of the antimatter that was thought to have disappeared was hiding around us in the form of anti-stars? Researchers from the Institute for Research in Astrophysics and Planetology are using the Fermi gamma-ray space telescope to put the most constraining limits ever on this hypothesis. The results of their work were published on April 20, 2021 in Physical Review D. What is anti

Europe’s Galileo braces for more emergency in-orbit maneuvers
Tuesday, 04 May 2021 17:07TAMPA, Fla. — Europe is preparing for more emergency in-orbit maneuvers in an increasingly crowded space environment, after its Galileo satellite navigation constellation had to dodge debris for the first time March 6.
The GSAT0219 satellite’s operations were suspended a day before the move, enabling it to steer clear of an inert Ariane 4 rocket fragment in medium Earth orbit (MEO).

Parker discovers natural radio emission in Venus' atmosphere
Tuesday, 04 May 2021 10:20During a brief swing by Venus, NASA's Parker Solar Probe detected a natural radio signal that revealed the spacecraft had flown through the planet's upper atmosphere. This was the first direct measurement of the Venusian atmosphere in nearly 30 years—and it looks quite different from Venus past. A study published today confirms that Venus' upper atmosphere undergoes puzzling changes over a solar cycle, the Sun's 11-year activity cycle. This marks the latest clue to untangling how and why Venus and Earth are so different.
Born of similar processes, Earth and Venus are twins: both rocky, and of similar size and structure.
