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.

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.

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.

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.

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.

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.  

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.

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).

The European Space Agency’s latest third generation Meteosat-I 1 weather satellite shows its stuff, with more to come.

NASA makes successful rover missions seem mundane. Spirit and Opportunity were wildly successful, and Curiosity and Perseverance would both be considered successes even if they stopped working today. But complex missions don’t succeed without rigorous testing.

After almost seventy years of study, astronomers are still fascinated by active galactic nuclei (AGN), otherwise known as quasi-stellar objects (or “quasars.”) These are the result of supermassive black holes (SMBHs) at the center of massive galaxies, which cause gas and dust to fall in around them and form accretion disks. The material in these disks is accelerated to close to the speed of light, causing it to release tremendous amounts of radiation in the visible, radio, infrared, ultraviolet, gamma-ray, and X-ray wavelengths. In fact, quasars are so bright that they temporarily outshine every star in their host galaxy’s disk combined.

Jupiter’s moon Io is the most volcanic world in the Solar System, with over 400 volcanoes. Some of them eject plumes as high as 500 km (300 mi) above the surface. Its surface is almost entirely shaped by all this volcanic activity, with large regions covered by silicates, sulphur, and sulphur dioxide brought up from the moon’s interior. The intense volcanic activity has created over 100 mountains, and some of them are taller than Mt. Everest.

The European Space Agency has been hosting a series of robotic teleoperation experiments where an astronaut abroad the ISS controls a robot back on the ground. We’ve previously reported on some of their successes. Now it’s time for the next round of experiments, with one individual astronaut on the ISS controlling four separate robots to perform a task back on Earth.

Remember the huge Tonga eruption in the South Pacific in January 2022? This underwater volcano sent tons of ash into the air. It also blew 146 teragrams of water into our atmosphere and the effect of the explosion reached space. It also made life very difficult for people on Tonga, wiping out their communications and sending tsunamis across the South Pacific.

Is it a multimedia art project? Or a rehearsal for alien contact? Let’s call it both: Researchers specializing in the search for extraterrestrial intelligence, or SETI, are working with a media artist to stage the receipt of an interstellar message — and a global effort to decode the message.

On Sunday, May 21, the 4-person crew of Axiom Mission 2 (Ax-2) blasted off to the International Space Station (ISS) on board a SpaceX Crew Dragon, and today, May 22, the private astronaut crew boarded the International Space Station for a scheduled 10-day stay.

Physics gets weird at the extremes. Astrophysics usually deals with the extremely large – large energies, large gravities, and lots and lots of stuff. Quantum mechanics, on the other hand, typically deals with the extremely small – quarks and other particles that are completely unseen by the human eye. So far, despite decades of trying, no Grand Unified Theory (or any other theory) combines these two opposed theories. This makes it all the more interesting that a team from the Purple Mountain Observatory of the Chinese Academy of Sciences proposed an idea that the interior cores of neutron stars, one of the most extreme examples of large extremes in the universe, might be made up of a type of tiny particle that makes up part of the “soup” of quantum mechanics called a strange quark. 

The universe is filled with things that go flash in the night. That includes fast radio bursts (FRBs). These are brilliant, powerful blips of radio emissions from distant and mysterious sources. Astronomers studying one called FRB 20190520B noticed something fascinating about its signals. They get polarized as they travel outward from the source.

There are some astronomical images that capture rapturous beauty, with their brilliant colors and interplay of shadow and light. A beautiful image can be enough to stir the soul, but in astronomy they often also have a story to tell. An example of this can be seen in a recent image released by NSF’s NOIRLab.

SpaceX’s second private astronaut mission to the International Space Station, (ISS), Axiom-2 aka Ax-2, which is sponsored Axiom Space, received a “go” for launch from NASA on May 15 followed by a stamp of approval from Mother Nature on May 19, and finally a completion of the Launch Readiness Review (LRR) on May 20. Liftoff is currently scheduled for May 21 at 5:37pm EDT (2:37pm PDT) from NASA Kennedy Space Center’s historic launch complex 39A, which was the launch site for all crewed Apollo-Saturn V launches starting with Apollo 8, along with Skylab, dozens of Space Shuttle launches, and starting in 2017 with SpaceX.

The James Webb Space Telescope (JWST) was designed to probe the mysteries of the Universe, not the least of which is what the first galaxies looked like. These galaxies formed during the Epoch of Reionization (aka. “Cosmic Dawn”), which lasted from about 100 to 500 million years after the Big Bang. By observing these galaxies and comparing them to ones that see closer to our own today, astronomers hope to test the laws of physics on the grandest of scales and what role (if any) Dark Matter and Dark Energy have played.
