Astronomy Jargon 101: Event Horizon
In this series we are exploring the weird and wonderful world of astronomy jargon! You won’t ever stop reading about today’s topic: event horizons!
An event horizon is the ultimate wall. It’s a boundary that separates one region of the universe from another. This separation is so complete that with event horizons it becomes utterly impossible for events on one side of the boundary to ever interact with or influence anything on the other side.
NASA asteroid detector 'looks up' to scan entire sky every 24 hours
The addition of two southern hemisphere telescopes will enable ATLAS to do full sky scans.
SpaceX is stacking its giant Starship ahead of Elon Musk's big update this week
SpaceX founder and CEO Elon Musk will have a nice visual aid to point to during his highly anticipated presentation on Thursday (Feb. 10).
Jupiter's auroras arise from a magnetic 'tug-of-war' with volcanic eruptions on its moon Io
Jupiter's auroras are caused by a cosmic game of "tug-of-war," fueled by volcanoes on the planet's innermost moon, Io.
UAE's Hope spacecraft marks 1 year in orbit around Mars
It's been a full year since the United Arab Emirates made history when its first-ever interplanetary mission slipped into orbit around Mars.
Comet Hale-Bopp: Facts about the bright and tragic comet
Hale-Bopp was an unusually bright comet that flew close to Earth in 1977. Tragically, Hale-Bopp also influenced the Heaven's Gate cult's mass suicide.
ESA hosts new office to coordinate global climate modelling push
Climate models are an important tool for scientists to understand our past climate and provide projections of future change. As such, they are in increasing demand as part of efforts to avert global warming and reduce risks associated with environmental change. To meet this demand, the World Climate Research Programme will open a new international office in the United Kingdom on 1 March 2022 that will coordinate the programme’s Climate Model Intercomparison Project.
SpaceX says a geomagnetic storm just doomed 40 Starlink internet satellites
SpaceX is losing 40 new Starlink internet satellites due to a geomagnetic storm.
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.
