We Finally Understand how Black Holes can Release Powerful Flares
While black holes might always be black, they do occasionally emit some intense bursts of light from just outside their event horizon. Previously, what exactly caused these flares had been a mystery to science. That mystery was solved recently by a team of researchers that used a series of supercomputers to model the details of black holes’ magnetic fields in far more detail than any previous effort. The simulations point to the breaking and remaking of super-strong magnetic fields as the source of the super-bright flares.
What happens at the center of a black hole?
At the center of a black hole, matter is compressed down to an infinitely tiny point, and all conceptions of time and space completely break down.
When is the midpoint of winter?
Winter's midpoint in 2022, contrary to the tradition of Candlemas or the annual extended forecast derived by Punxsutawney Phil, was on Feb. 3.
Comet impact may have triggered decline of Ohio's Hopewell people 1,600 years ago
Researchers think that comet fragments may have exploded over Ohio 1,600 years ago, triggering a violent airburst and starting wildfires that devastated the Hopewell people's crops and the landscape.
Solar storm dooms 40 new Starlink satellites

SpaceX said Tuesday a solar storm causing more atmospheric drag in low Earth orbit will destroy as many as 40 of 49 new Starlink internet satellites launched from Florida last week.
Paint it black: behind the James Webb Space Telescope's signature color
NASA's James Webb Space Telescope has to stay super cool to observe the cosmos. How does it beat the heat? Black paint.
Why are Neptune and Uranus Different Colors?
Uranus and Neptune are similar planets in many ways. Both are ice giant worlds, both have atmospheres rich in methane, and both have a bluish color. But while Uranus has a pale blue-green hue, Neptune has a deep blue color. But why? Why would two planets so similar in size and composition appear so different? According to a recent study, the answer lies in their aerosols.
Mars rover Perseverance sets distance record on the Red Planet
The rover topped 800 feet with a self-drive function.
Mars helicopter Ingenuity aces 19th flight after historic Red Planet weather delay
Ingenuity aced a 100-second sortie on Tuesday (Feb. 8), its 19th Red Planet flight overall but its first since Dec. 15. A dust storm pushed the liftoff date back by more than a month.
Massive Rocky Planets Probably Don’t Have big Moons
The Moon has orbited Earth since the Solar System’s early days. Anyone who’s ever spent time at the ocean can’t fail to notice the Moon’s effect. The Moon drives the tides even in the world’s most remote inlets and bays. And tides may be vital to life’s emergence.
Monitoring crop health across the Netherlands
The Copernicus Sentinel satellite missions measure and image our planet in different ways to return a wealth of complementary information so that we can understand and track how our world is changing, and how to better manage our environment and resources. Thanks to the benefits of different types of data from two particular Copernicus Sentinel missions and an ingenious new dataset tool, people working in the agriculture sector, but who are not satellite data experts, can monitor the health and development of crops, right down to each crop in individual fields.
NASA picks Lockheed Martin to build rocket to carry Mars samples back to Earth
Lockheed Martin will build the Mars Ascent Vehicle, a small rocket that will launch pristine Red Planet samples back toward Earth a decade or so from now.
Astronomy Jargon 101: Eccentricity
In this series we are exploring the weird and wonderful world of astronomy jargon! You’ll be sure to find your center with today’s topic: eccentricity!
Eccentricity is a measure of how circular an orbit is. An eccentricity of 0 means that the orbit a perfect circle. Anything between 0 and 1 is an elliptical orbit. An eccentricity of exactly 1 gives a parabola, which isn’t much or an orbit at all, but rather an escape trajectory. Finally, a value greater than 1 is an orbit with the shape of a hyperbola, which is also an escape trajectory.
Rugged Mars has taken big bites out of the Curiosity rover's wheels (photos)
NASA's Curiosity rover has left plenty of marks on Mars over the past nine-plus years, and the Red Planet is returning the favor.
New Startup Quantum Space is Planning to Build a Robotic Outpost Near the Moon
The Moon is sure to be a hotspot of economic activity as human commercial endeavors start to expand into space. Not only is it a ball of resources with a relatively small gravity well, but it also happens to be our nearest neighbor. But to unlock that potential, companies will have to build up an infrastructure that will allow for the exploitation of those resources. Enter Quantum Space, a new start-up from a group of heavy-hitting space experts looking to help make that potential a reality – by building a robotic spaceport around the moon.
The Comfort and Delight of Celestial “Reruns”
Seeing the same target again has the comfort of a beloved rerun, while offering the opportunity for new discoveries.
A rogue rocket is on course to crash into the moon. It won't be the first.
Some astronomers say the collision is "not a big deal," but to a space archaeologist like me it's quite exciting.
The 'morning star' Venus returns to the dawn sky this month
The planet Venus has returned to the early morning sky and has established itself as a dazzling morning lantern, emerging into view from beyond the east-southeast horizon before 5 a.m. local standard time.
India to attempt its next moon landing with Chandrayaan 3 launch in August
India plans to give landing on the moon a second try with its Chandrayaan 3 mission, which is now targeted to launch in August.
Russia wants to speed up space station cargo deliveries with shorter, one-orbit flights
The Russian space agency released a proposal to allow its Progress cargo ships to arrive in a single orbit, an unprecedented two-hour flight.
