Each year, the Hubble Space Telescope focuses on the giant planets in our Solar System when they’re near the closest point to Earth, which means they’ll be large and bright in the sky. Jupiter had its photos taken on January 5-6th, 2024, showing off both sides of the planet. Hubble was looking for storm activity and changes in Jupiter’s atmosphere.

Astronomers using the Very Large Telescope in Chile have now completed one of the largest surveys ever to hunt for planet-forming discs. They were able to find dozens of dusty regions around young stars, directly imaging the swirling gas and dust which hints at the locations of these new worlds.
Just like the wide variety in the types of exoplanets that have been discovered, these new data and stunning images show how protoplanetary systems are surprisingly diverse, with different sizes and shapes of disks.
In research presented in three new papers, researchers imaged 86 young stars and found 62 of them had a wide range of star-forming regions surrounding them. The astronomers say this study provides a wealth of data and unique insights into how planets arise in different regions of our galaxy.

Hubble and JWST are busily scanning the sky, sending home enormous amounts of data. They shift from target to target, completing the required observations.
But have you ever wondered what those two space telescopes are doing right at this moment? Now, you can do just that at the new Space Telescope Live website. It will show you what each observatory is scanning, where the objects are in the sky, and what researchers hope to learn. You can even go back or forward in time and see what each telescope has been looking at in the past or what observations are coming up.

Here’s a front row seat on what it would be like to return to Earth inside a space capsule. Varda Space Industries’ small W-1 spacecraft successfully landed at the Utah Test and Training Range on February 21, 2024. A camera installed inside the cozy 90 cm- (3 ft)-wide capsule captured the entire stunning reentry sequence, from separation from the satellite bus in low Earth orbit (LEO) to the fiery re-entry through Earth’s atmosphere, to parachute deploy, to the bouncy landing.
At the end of this 5-minute video, you’ll see a pair legs with mud-caked shoes approach to gather the parachute and retrieve the capsule. Not only is there video, but sound as well. And the sounds of reentry and landing are what grabs you!

For decades, astronomers have said that one of the most optimal places to build large telescopes is on the surface of the Moon. The Moon has several advantages over Earth- and space-based telescopes that make it worth considering as a future home for giant observatories. A new paper lists all the advantages, including how telescopes on the lunar surface wouldn’t be blocked by an atmosphere or impacted by wind, and how the low gravity would allow gigantic structures to be built that could be upgraded over time by astronauts.
“Progress on the big questions in astronomy, such as life on certain exoplanets or dark matter, will ultimately require high angular resolution, a large collecting area and access to the full optical spectrum,” write French astronomers Jean Schneider, Pierre Kervella, and Antoine Labeyrie. “All astronomy will benefit from the advantages provided by the localization on the Moon.”
And even though it might be decades before we have a permanent presence on the Moon, the astronomers suggest we should start with small telescopes now.

Supermassive black holes are messy feeders, and when they’re gorging on too much material, they can hurl high-energy jets into the surrounding Universe. Astronomers have found one of the most powerful eruptions ever seen, emanating from a black hole 3.8 billion light-years away. The powerful jets are blowing out cavities in intergalactic space and triggering the formation of a huge chain of star clusters.

Japan successfully tested its new flagship H3 rocket after an earlier version failed last year. The rocket lifted off from the Tanegashima Space Center on Saturday, February 17, reaching an orbital altitude of about 670 kilometers (420 miles). It deployed a set of micro-satellites and a dummy satellite designed to simulate a realistic payload.
With the successful launch of the H3, Japan will begin transitioning away from the previous H-2A rocket which has been in service since 2001 and is set to be retired after two more launches. Several upcoming missions depend on the H3, so this successful test was vital.

There’s a problem with the Perseverance rover. One of its instruments, the laser-shooting SHERLOC, which is mounted on the end of the robotic arm, has a dust cover that is supposed to protect the instrument when it’s not in use. Unfortunately, the cover has been stuck open, and that can allow dust to collect on the sensitive optics. The cover is partially open, so the rover can’t use its laser on rock targets or collect mineral spectroscopy data. NASA engineers are investigating the problem and are hoping to devise a solution.

Although the U.S. Space Force is tasked with military operations in regards to space, they’ve never actually sent one of their own into orbit. This week, the agency announced that Col. Nick Hague will launch to the International Space Station in August 2024 to pilot the Crew-9 mission, as part of SpaceX’s ninth crew rotation to the ISS for NASA. He’ll join two NASA astronauts and a cosmonaut on the trip to space and then work as a flight engineer, spending six months on the station doing research and operations activities.

Swedish astronaut Marcus Wandt took control of a series of robots in Germany while on board the International Space Station, zipping around the Earth at 28,000 kilometers per hour (17,500 mph.) Researchers want to understand how time delays can affect the remote control of robots from an orbiting platform. Future astronauts could control rovers on the Moon’s or Mars’s surface from a spacecraft in orbit. Until now, only wheeled rovers have been part of the tests, but now they have added a dog-like robot called Bert.
