The prospect of actually resolving the event horizon of black holes feels like the stuff of science fiction yet it is a reality. Already the Event Horizon Telescope (EHT) has resolved the horizon of the black holes at the centre of the Milky Way and M87. A team of astronomers are now looking to the next generation of the EHT which will work at multiple frequencies with more telescopes than EHT. A new paper suggests it may even be possible to capture the ring where light goes into orbit around the black hole at the centre of the Milky Way.

Rapidly spinning dead stars could unveil dark matter secrets
"Cosmic lighthouses" comprised of rapidly spinning dead stars that blast out radiowaves could be used to shed new light on dark matter, the universe's most mysterious "stuff."
Happy 25th anniversary, Chandra! NASA celebrates with 25 breathtaking images from flagship X-ray observatory
To celebrate the 25th anniversary of the flagship Chandra X-ray observatory, NASA has released 25 never-before-seen images of iconic astronomical objects.
June 2024 featured record-breaking heat and billion-dollar weather disasters, NOAA says
The U.S. just suffered its second-hottest June in 130 years. The month also featured four new billion-dollar weather and climate disasters.
The Ultraviolet Habitable Zone Sets a Time Limit on the Formation of Life
The field of extrasolar planet studies has grown exponentially in the past twenty years. Thanks to missions like Kepler, the Transiting Exoplanet Survey Satellite (TESS), and other dedicated observatories, astronomers have confirmed 5,690 exoplanets in 4,243 star systems. With so many planets and systems available for study, scientists have been forced to reconsider many previously-held notions about planet formation and evolution and what conditions are necessary for life. In the latter case, scientists have been rethinking the concept of the Circumsolar Habitable Zone (CHZ).
21 'one-in-a-million' extreme dead stars found hiding around sun-like stars
Astronomers have detected 21 rare systems with widely separated neutron stars and sun-like stars. These binaries are "one in a million" and challenge dead star binary formation models.
Curiosity Drives Over a Rock, Cracking it Open and Revealing an Amazing Yellow Crystal
On May 30th, the Mars Curiosity rover was just minding its own business exploring Gediz Vallis when it ran over a rock. Its wheel cracked the rock and voila! Pure elemental sulfur spilled out. The rover took a picture of the broken rock about a week later, marking the first time sulfur has been found in a pure form on Mars.
SpaceX makes Starlink Roam available throughout the US
Described as "high-speed internet on the go," SpaceX's Starlink Mini is now available from coast to coast, bringing users a world-wide connection from space.
Producing Oxygen From Rock Is Harder In Lower Gravities
One of the challenges engineers face when developing technologies for use in space is that of different gravities. Mostly, engineers only have access to test beds that reflect either Earth’s normal gravity or, if they’re fortunate, the microgravity of the ISS. Designing and testing systems for the reduced, but not negligible, gravity on the Moon and Mars is much more difficult. But for some systems, it is essential. One such system is electrolysis, the process by which explorers will make oxygen for astronauts to breathe on a permanent Moon or Mars base, as well as critical ingredients like hydrogen for rocket fuel. To help steer the development of systems that will work in those conditions, a team of researchers led by computational physicist Dr. Paul Burke of the Johns Hopkins University Applied Physics Laboratory decided to turn to a favorite tool of scientists everywhere: models.
SpaceX wins $113 million contract to launch advanced NOAA climate satellite
SpaceX has won a $113 million contract to launch NOAA's JPSS-4 climate and weather satellite. Liftoff is targeted for 2027.

Alien weather report: James Webb Space Telescope detects hot, sandy wind on 2 brown dwarfs
The JWST's infrared vision has seen deep into the stormy atmosphere of two brown dwarfs that form the third closest system to the sun.
Scientists waited ages to find a 'missing link' black hole — then stumbled upon 2
A missing link black hole that sits in the mass gap between stellar-mass black holes and supermassive black holes is "parked" right by the Milky Way's central black hole, Sagittarius A*.

SpaceX Starlink satellites made 50,000 collision-avoidance maneuvers in the past 6 months. What does that mean for space safety?
Satellites in SpaceX's Starlink megaconstellation made nearly 50,000 collision-avoidance maneuvers in the last six months, about double the number made in the previous half-year.

HBO's 'Wild Wild Space' provides an inside look at the private space race (review)
A review of HBO’s new documentary "Wild Wild Space," which chronicles the private space race via three of its high-profile players.
The Entrance of a Lunar Lava Tube Mapped from Space
Craters are a familiar sight on the lunar surface and indeed on many of the rocky planets in the Solar System. There are other circular features that are picked up on images from orbiters but these pits are thought to be the collapsed roofs of lava tubes. A team of researchers have mapped one of these tubes using radar reflection and created the first 3D map of the tube’s entrance. Places like these could make ideal places to setup research stations, protected from the harsh environment of an alien world.
Moon Dust Could Contaminate Lunar Explorers’ Water Supply
Water purification is a big business on Earth. Companies offer everything from desalination to providing just the right pH level for drinking water. But on the Moon, there won’t be a similar technical infrastructure to support the astronauts attempting to make a permanent base there. And there’s one particular material that will make water purification even harder – Moon dust.
