The Black Hole Files with Camille Carlisle
Black Holes Grow by Gas, Not Mergers, Most of Their Lives
Calculations suggest how black holes have amassed mass and predict what the black holes’ spins should be if this picture is correct.
Ryugu May Have Skirted Close to the Sun
Observations by the Japanese Hayabusa 2 spacecraft show subtle color differences, indicating something has reddened the asteroid’s surface.
Closest Black Hole to Earth? Maybe
An international team of astronomers says that they’ve discovered the closest black hole to Earth — an invisible object dancing with two large, bright stars 1,000 light-years away.
Mismatched Black Holes Merge
For the first time, the LIGO and Virgo gravitational-wave detectors have "heard" gravitational waves from an unequal pair of black holes.
Black Hole Changes Star’s Orbit in Gravity Test
A long-awaited measurement indicates that a star whizzing around the Milky Way’s supermassive black hole has changed its trajectory.
Event Horizon Telescope Finds Bent Jet Near Black Hole
Observations from the worldwide network of radio telescopes show the fire hose of plasma shooting from a distant galaxy does something strange near its source.
Astronomers Make It Rain, Search for Gin and Vampires
As is customary on the first day of April, scientists posted research that breaks out of the box peer-review normally keeps it in.

Scientists Predict Countless Rings of Light Encircle Black Holes
Detailed calculations reveal a surprise about how black holes bend light around themselves, opening a new possibility for future observations.
NASA’s Insight Detects Many Marsquakes on the Red Planet
Persistent tremors on Mars suggest the planet’s interior is cooling and hint that there might be a pocket of magma beneath the surface.
Nearby Stellar Nurseries Ride a Giant Wave
Astronomers have found a gigantic, undulating wave of stellar nurseries in our galaxy, just outside the Sun’s orbit in the spiral disk.
60-Second Astro News: Planets in Tight Quarters & Kuiper Belt Forays
Astronomers have calculated the loss of planets around stars in globular clusters, and New Horizons returns observations of worlds in the outer solar system.
Baby Stars Found in Ancient Part of Our Galaxy
Ground- and space-based observations have revealed a group of stars at the head of the giant stream of gas burrowing its way through the Milky Way.
More Big Black Holes Found in Small Galaxies
In the quest to discover how massive black holes form, astronomers have spotted several of these objects in some of the smallest galaxies yet found to host them.
Asteroid Bennu’s Activity Still a Mystery
The near-Earth asteroid constantly shoots out rocks, leaving planetary scientists perplexed.

Bubbles, Heated Clouds Point to Active Past for Galactic Center
Two studies support the suspicion that our galaxy’s black hole had one or more outbursts a few million years ago.
More Black Hole Mergers Found in LIGO Data
Analysis by an independent team has ferreted out seven candidates for gravitational-wave events from merging black holes.

Video: Black Hole Warps Light
The hypnotizing effect of a black hole on its surroundings appears to dramatic effect in this simulation.
Video: Chasing Dust Devils
Scientists are flying instrument-laden drones through whirlwinds on Earth to better understand their counterparts on other worlds in the solar system.
60-Second Astro News: Black Hole Hubbub
The Milky Way's black hole' flares unexpectedly, a distant black hole gets the hiccups, and a reanalysis of LIGO data shows the first detection of black hole "ringdown."
Warped Milky Way in 3D
Astronomers have used pulsating stars to trace the crooked shape of our galaxy’s disk.
