The European Space Agency’s latest third generation Meteosat-I 1 weather satellite shows its stuff, with more to come.
You’ve never seen the Earth and its complex weather systems like this. The European Space Agency (ESA) recently unveiled views from their latest weather satellite in geostationary (GEO) orbit, Meteosat Third Generation Imager-1 (MTG-I 1).

New images that combine data from NASA’s Chandra X-ray Observatory and the James Webb Space Telescope (JWST) JWST have just been released! The images feature four iconic astronomical objects, showcasing the capabilities of these observatories by combining light in the visible, infrared, and X-ray wavelengths. These include the NGC 346 star cluster located in the Small Magellanic Cloud (SMC), the NGC 1672 spiral galaxy, the Eagle Nebula (Messier 16, or M16), and the spiral galaxy Messier 74 (aka. the Phantom Galaxy).
These objects were made famous by the venerable Hubble Space Telescope, which took pictures of them between 1995 and 2005. Since it commenced operations, the JWST has conducted follow-up observations that provided a sharper view of these objects that captured additional features. Hubble and the JWST even teamed up to provide a multi-wavelength view of the Phantom Galaxy last year. By adding Chandra’s famed X-ray imaging capabilities to Webb’s sensitivity and infrared light, these latest images provide a new glimpse of these objects, revealing both faint and more energetic and powerful features.

In the early days of spaceflight, just getting a satellite into Earth’s orbit was an accomplishment. In our era, landing rovers on other planets and bringing samples home from asteroids is the cutting edge. But the next frontier is rapidly approaching, when astronauts will stay for long periods of time on the Moon and hopefully Mars.
But before we can send people to those dangerous environments, the Artemis partner space agencies have to know how to keep them safe. An important part of that is simulating the conditions on the Moon and Mars.

Asteroid mining is slowly but surely coming closer to reality. Many start-ups and governmental agencies alike are getting in on the action. But plenty of tools that would help get this burgeoning industry off the ground are still unavailable. One that would be particularly useful is a list of potential candidate asteroids to visit. While the information has been available in various places, no one has yet combined it into a single, searchable database until now.

After a two-year hiatus, Virgin Galactic’s SpaceShipTwo VSS Unity resumed flying crew members beyond a 50-mile-high space milestone, marking the end of a years-long flight test program and setting the stage for the start of commercial service as soon as next month.
It was the first launch of the Unity rocket plane from its VMS Eve carrier airplane since July 2021, when company founder Richard Branson took a ride. Branson said he was “proud” to be watching from Spaceport America in New Mexico when Unity took flight.
During today’s suborbital flight test, known as Unity 25, the rocket plane sent two pilots and four other Virgin Galactic employees to a maximum height of 54.2 miles, at a top speed of Mach 2.94.

New images from NASA’s Lunar Reconnaissance Orbiter (LRO) appear to show the crash site where the Japanese Hakuto-R Mission 1 lunar lander impacted the surface of the Moon a month ago.
The refrigerator-sized HAKUTO-R was built by the startup company iSpace and was launched in December 2022 with the goal of becoming the first commercial lunar lander to touch down safely on the Moon. However, during landing operations on April 25, 2023, communications ceased just moments before touchdown should have occurred, and the lander was presumed lost.

Have you noticed a lack of gravitational wave announcements the past couple of years? Well, now it is time to get ready for an onslaught, as the Laser Interferometric Gravitational-Wave Observatory (LIGO) starts a new 20-month observation run today, May 24th after a 3-year hiatus.
LIGO has been offline for the last three years, getting some serious new upgrades. One upgrade, called “quantum squeezing,” reduces detector noise to improve its ability to sense gravitational waves.
Astronomers expect this upgrade could double the sensitivity of LIGO. This will allow black hole mergers to be seen more clearly, and it could also allow LIGO to see mergers that are fainter or farther away. Or, perhaps it could even detect new kinds of mergers that have never been seen before.

They’re affectionately known as “pillownauts,” volunteers who commit to spending weeks in bed to advance research into astronaut health. While bedridden, the pillownauts will lie with their heads tilted at 6° below the horizontal with their feet up to increase blood flow to their heads. They also perform work-related tasks, are subject to regular medical exams, and take their meals, showers, and bathroom breaks, all while remaining in bed. The purpose of this research is to simulate the effects of weightlessness on the human body, including muscle atrophy, bone density loss, and cognitive effects.
The European Space Agency (ESA) recently kicked off another round of pillownaut research, the Bed Rest with Artificial gravity and Cycling Exercise (BRACE) study, at the Institute for Space Medicine and Physiology (MEDES) in Toulouse, France. For this study, twelve volunteers will remain inclined (with their heads below their feet) for sixty days and exercise using cycles adapted to their beds and centrifuges that simulate gravity. Beyond measuring the effects of microgravity on astronaut health, this study also aims to measure the effectiveness of countermeasures used to address them.

Uranus takes 84 years to orbit the Sun, and so that last time that planet’s north polar region was pointed at Earth, radio telescope technology was in its infancy.
But now, scientists have been using radio telescopes like the Very Large Array (VLA) the past few years as Uranus has slowly revealing more and more of its north pole. VLA microwave observations from 2021 and 2022 show a giant cyclone swirling around this region, with a bright, compact spot centered at Uranus’ pole. Data also reveals patterns in temperature, zonal wind speed and trace gas variations consistent with a polar cyclone.

Most black holes are stellar mass black holes. They’re created when a star several times more massive than our Sun reaches the end and collapses in on itself. There are also supermassive black holes (SMBH,) the behemoths at the center of galaxies that can boast billions of times more mass than the Sun.
But where are the intermediate-mass black holes?
