Tracing Interstellar Dust Back to the Solar System’s Formation

Department of Energy, Office of Science

This study is the first to confirm dust particles pre-dating the formation of our solar system. Further study of these materials will enable a deeper understanding of the processes that formed and have since altered them.

Gas ‘Waterfalls’ Reveal Infant Planets around Young Star

National Radio Astronomy Observatory

For the first time, astronomers using ALMA have witnessed 3D motions of gas in a planet-forming disk. At three locations in the disk around a young star called HD 163296, gas is flowing like a waterfall into gaps that are most likely caused by planets in formation. These gas flows have long been predicted and would directly influence the chemical composition of planet atmospheres. This research is published in the latest issue of the journal Nature.

Two Brookhaven Lab Scientists Named DOE Office of Science Distinguished Fellows

Brookhaven National Laboratory

Scientists from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have garnered two out of five "Distinguished Scientists Fellow" awards announced today by the DOE's Office of Science. Theoretical physicist Sally Dawson, a world-leader in calculations aimed at describing the properties of the Higgs boson, and José Rodriguez, a renowned chemist exploring and developing catalysts for energy-related reactions, will each receive $1 million in funding over three years to pursue new research objectives within their respective fields.

Hubble Observes First Confirmed Interstellar Comet

Space Telescope Science Institute (STScI)

Hubble has taken the sharpest view to date of interstellar comet 2I/Borisov whose speed and trajectory indicate it has come from beyond our solar system. The image, taken October 12, 2019, reveals a central concentration of dust around the comet's nucleus.

Newswise: Going Against the Flow Around a Supermassive Black Hole

Article ID: 720748

Going Against the Flow Around a Supermassive Black Hole

National Radio Astronomy Observatory

At the center of a galaxy called NGC 1068, a supermassive black hole hides within a thick doughnut-shaped cloud of dust and gas. When astronomers used the Atacama Large Millimeter/submillimeter Array (ALMA) to study this cloud in more detail, they made an unexpected discovery that could explain why supermassive black holes grew so rapidly in the early Universe. “Thanks to the spectacular resolution of ALMA, we measured the movement of gas in the inner orbits around the black hole,” explains Violette Impellizzeri of the National Radio Astronomy Observatory (NRAO), working at ALMA in Chile and lead author on a paper published in the Astrophysical Journal. “Surprisingly, we found two disks of gas rotating in opposite directions.”

Analysis of Galileo’s Jupiter Entry Probe Reveals Gaps in Heat Shield Modeling

American Institute of Physics (AIP)

The entry probe of the Galileo mission to Jupiter entered the planet’s atmosphere in 1995 in fiery fashion, generating enough heat to cause plasma reactions on its surface. The data relayed about the burning of its heat shield differed from the effects predicted in fluid dynamics models, and new work examines what might have caused such a discrepancy.
