- Hubble data confirms galaxies lacking dark matteron June 17, 2021 at 3:00 pm
The most accurate distance measurement yet of ultra-diffuse galaxy (UDG) NGC1052-DF2 (DF2) confirms beyond any shadow of a doubt that it is lacking in dark matter. The newly measured distance of 22.1 +/-1.2 megaparsecs was obtained by an international team of researchers led by Zili Shen and Pieter van Dokkum of Yale University and Shany Danieli, a NASA Hubble Fellow at the Institute for Advanced Study.
- Study of young, chaotic star system reveals planet formation secretson June 17, 2021 at 2:26 pm
A team of scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) to study the young star Elias 2-27 have confirmed that gravitational instabilities play a key role in planet formation, and have for the first time directly measured the mass of protoplanetary disks using gas velocity data, potentially unlocking one of the mysteries of planet formation. The results of the research are published today in two papers in The Astrophysical Journal.
- Juno detects Jupiter’s highest-energy ionson June 17, 2021 at 2:26 pm
Jupiter’s planetary radiation environment is the most intense in the solar system. NASA’s Juno spacecraft has been orbiting the planet closer than any previous mission since 2016, investigating its innermost radiation belts from a unique polar orbit. The spacecraft’s orbit has enabled the first complete latitudinal and longitudinal study of Jupiter’s radiation belts. Becker et al. leverage this capability to report the discovery of a new population of heavy, high-energy ions trapped at Jupiter’s midlatitudes.

- Study points to a seed black hole produced by a dark matter halo collapseon June 16, 2021 at 8:02 pm
Supermassive black holes, or SMBHs, are black holes with masses that are several million to billion times the mass of our sun. The Milky Way hosts an SMBH with mass a few million times the solar mass. Surprisingly, astrophysical observations show that SMBHs already existed when the universe was very young. For example, a billion solar mass black holes are found when the universe was just 6% of its current age, 13.7 billion years. How do these SMBHs in the early universe originate?
- The give and take of mega-flares from starson June 16, 2021 at 7:58 pm

- Study investigates the behavior of magnetar SGR J1745–2900on June 16, 2021 at 3:05 pm
Using NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR), Russian astronomers have investigated the behavior of a magnetar known as SGR J1745–2900 after its outburst in April 2013. Results of the study, published June 9 on arXiv.org, could be essential to better understand the nature of this magnetar.

- Mystery of Betelgeuse’s dip in brightness solvedon June 16, 2021 at 3:00 pm
When Betelgeuse, a bright orange star in the constellation of Orion, became visibly darker in late 2019 and early 2020, the astronomy community was puzzled. A team of astronomers have now published new images of the star’s surface, taken using the European Southern Observatory’s Very Large Telescope (ESO’s VLT), that clearly show how its brightness changed. The new research reveals that the star was partially concealed by a cloud of dust, a discovery that solves the mystery of the Great Dimming of Betelgeuse.

- Space scientists solve a decades-long gamma-ray burst puzzleon June 16, 2021 at 12:00 pm
An international team of scientists, led by astrophysicists from the University of Bath in the UK, has measured the magnetic field in a far-off Gamma-Ray Burst, confirming for the first time a decades-long theoretical prediction—that the magnetic field in these blast waves becomes scrambled after the ejected material crashes into, and shocks, the surrounding medium.
- Total solar eclipses shine a light on the solar wind with help from NASA’s ACE missionon June 16, 2021 at 11:55 am
From traversing sand dunes in the Sahara Desert to keeping watch for polar bears in the Arctic, a group of solar scientists known as the “Solar Wind Sherpas” led by Shadia Habbal, have traveled to the ends of the Earth to scientifically observe total solar eclipses—the fleeting moments when the Moon completely blocks the Sun, temporarily turning day into night. With the images, they’ve uncovered a surprising finding about the Sun’s wind and its wispy outer atmosphere—the corona—which is only visible in its entirety during an eclipse.
- Rare triple galaxy merger with at least two supermassive black holeson June 16, 2021 at 11:09 am
One of the best things about that universe is that there is so much to it. If you look hard enough, you can most likely find any combination of astronomical events happening. Not long ago, we reported on research that found seven separate instances of three galaxies colliding with one another. Now, a team led by Jonathan Williams of the University of Maryland has found another triple galaxy merging cluster, but this one might potentially have two active supermassive black holes, allowing astronomers to peer into the system dynamics of two of the universe’s most extreme objects running into one another.
- China to launch first crew to new space station on Thursdayon June 16, 2021 at 6:10 am

- Coronal mass ejections and cosmic ray observations at Syowa Stationon June 15, 2021 at 4:42 pm
Solar activities, such as CME(Coronal Mass Ejection), cause geomagnetic storms that disturb the Earth’s magnetosphere. Geomagnetic storms can affect GPS positioning, radio communication, and power transmission system. Solar explosions also emit radiation, which can cause satellite failures, radiation exposure to aircraft crew, and space activity. Therefore, it is important to understand space weather phenomena and their impact on the Earth.
- Observations detect a brown dwarf orbiting the star TOI–1278on June 15, 2021 at 3:10 pm
An international team of astronomers reports the discovery of a companion to the M dwarf star known as TOI–1278. The newly found object turns out to be a brown dwarf nearly 20 times as massive as Jupiter. The finding is detailed in a paper published June 8 on the arXiv pre-print server.
- Largest structures in the universe show clear light-shifted signal of rotationon June 15, 2021 at 2:37 pm
By mapping the motion of galaxies in huge filaments that connect the cosmic web, astronomers at the Leibniz Institute for Astrophysics Potsdam (AIP), in collaboration with scientists in China and Estonia, have found that these long tendrils of galaxies spin on the scale of hundreds of millions of light years. A rotation on such enormous scales has never been seen before. The results published in Nature Astronomy signify that angular momentum can be generated on unprecedented scales.

- Black holes help with star birthon June 14, 2021 at 3:14 pm
Research combining systematic observations with cosmological simulations has found that, surprisingly, black holes can help certain galaxies form new stars. On scales of galaxies, the role of supermassive black holes for star formation had previously been seen as destructive—active black holes can strip galaxies of the gas that galaxies need to form new stars. The new results, published in the journal Nature, showcase situations where active black holes can, instead, “clear the way” for galaxies that orbit inside galaxy groups or clusters, keeping those galaxies from having their star formation disrupted as they fly through the surrounding intergalactic gas.
