Supermassive Black Holes May Enhance Star Formation (opens the original)
Read excerpt
The black holes at the hearts of galaxies get the credit and/or blame for a lot of things in their hosts. For example, they take the blame for gobbling up star-forming material, effectively "quenching" starbirth in some areas of galaxies. On the bright side, it now turns out that some of them may be commonly participating in the births of stars, too. Thanks to a series of observations made using the Very Large Telescope in Chile, research by Harvard Center for Astrophysics graduate student Peixi
Mars Has a Warm Region Inside (opens the original)
Read excerpt
Something deep inside Mars has scientists looking for clues to its internal evolution. A team at the University of Arizona and Brown University, led by Alexander Byrne, used a technique called "tidal tomography" to probe a heat anomaly in the southern hemisphere mantle. It turns out this subsurface region measures about 200 to 400 degrees Celsius warmer than the rest of the mantle. That warm spot may contain information about heating inside the planet and how Mars has changed over its lifetime.
How the Infant Universe Got Its First Heavy Elements (opens the original)
Read excerpt
Way back in the earliest epochs of the Universe, the Big Bang was followed by a period called the Cosmic Dark Ages. It was a time when the cosmic soup of primordial particles was so thick that light couldn't propagate. Hence the term "dark"; also, because, even with our best telescopes, we can't see "into" that epoch. Although we don't have a definite "century by century" timeline of activity, it doesn't mean this period of history didn't lead to something interesting. Gravity (and the action of
Is a Sea Change Coming for New Horizons Heliospheric Science? (opens the original)
Read excerpt
If you visit the New Horizons mission website frequently, you'll notice that the spacecraft continues to generate excellent science as it plows its way through the Kuiper Belt. It recently woke up from its latest hibernation period in good health and is transmitting data it gathered back to Earth. The spacecraft, in addition to studying the Jupiter system in 2007, the Pluto system in 2015, and the Kuiper Belt Object Arrokoth in early 2019, has been doing some other fascinating solar system scien
What Can Happen When a Rapidly Spinning Star Meets a Black Hole? (opens the original)
Read excerpt
Astrophysicists at Syracuse University in New York think they've found a hitherto-hidden explanation for strange activity during so-called repeating partial Tidal Disruption Events (rpTDEs). These are interactions between a supermassive black hole and a star that wanders too close for comfort, but not close enough to get swallowed up. The "repeating" part of the event occurs because the near-misses occur over and over again. As the star gets closer to the black hole during its orbit, the extreme
