A new image from the Event Horizon Telescope (EHT) collaboration— which includes scientists from the Center for Astrophysics | Harvard & Smithsonian (CfA)— has uncovered strong and organized magnetic fields spiraling from the edge of the supermassive black hole Sagittarius A* (Sgr A*). Seen in polarized light for the first time, this new view of the monster lurking at the heart of the Milky Way Galaxy has revealed a magnetic field structure strikingly similar to that of the black hole at the center of the M87 galaxy, suggesting that strong magnetic fields may be common to all black holes. This similarity also hints toward a hidden jet in Sgr A*.
On Monday, April 8, much of the United States will have the opportunity to witness a partial or total eclipse.
As you gaze into the night sky, stars look like tiny, glowing pinpricks shining through the dark. But inside those stars, reactions occur that produce staggering amounts of energy. All stars – including our sun – produce energy through a powerful reaction called fusion.
A Hubble telescope survey has found that brown dwarfs—objects smaller than stars but bigger than planets—live a lonely life as they age. Over time they lose the companion brown dwarf that was born alongside them and the objects drift their separate ways.
On April 8, millions of observers in Ohio will witness a total solar eclipse, a rare celestial event that promises to be an otherworldly experience.
When a star goes supernova, a massive burst of neutrinos is the first signal that can escape the density of the collapsing star. Detecting and analyzing this phenomenon in real time would allow us insight into stellar dynamics and, potentially, black hole formation.

For telescopes operating in the vacuum of space, or optical equipment in extreme environments, existing coatings are often insufficient. In the Journal of Vacuum Science & Technology Aresearchers in China turned to atomic layer deposition and developed an ultrablack thin-film coating for aerospace-grade magnesium alloys. The team used alternating layers of aluminum-doped titanium carbide and silicon nitride and together the materials prevent nearly all light from reflecting off the coated surface. The coating absorbs 99.3% of light while being durable enough to survive in harsh conditions.
In the astronomy field, the term “nearby” is quite relative. Neighboring galaxies to our home galaxy, the Milky Way, are a few million light-years away. In contrast, some of the most distant galaxies ever detected, closer to the Big Bang, are billions of light-years away.
Space Telescope Live provides an interactive way to explore the most accurate, up-to-date, publicly available information on current, past, and upcoming observations by NASA’s Hubble and Webb space telescopes.
The Universe is almost inconceivably vast. So is the amount of data astronomers collect when they study it.

Scientists at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory are working on ways to improve thrusters for satellites operating in very low orbit around the Earth. The researchers believe they can make satellites that weigh less, last longer and cost less by creating thrusters that use the air around them instead of having to carry its own supply of fuel. PPPL’s diagnostics will be used to evaluate this innovative thruster concept and characterize key physical processes involved in its operation.
Dark matter comprises over 80% of all matter in the cosmos but is invisible to conventional observation, because it seemingly does not interact with light or electromagnetic fields. Now Dr. Sukanya Chakrabarti, the Pei-Ling Chan Endowed Chair in the College of Science at The University of Alabama in Huntsville (UAH), along with lead author Dr. Tom Donlon, a UAH postdoctoral associate, have written a paper to help illuminate just how much dark matter there is in our galaxy and where it resides by studying the gravitational acceleration of binary pulsars. Chakrabarti gave a plenary talk on this work and other methods to measure galactic accelerations at the 243rd meeting of the American Astronomical Society in New Orleans in January.
