A team of astronomers using the Chinese Insight-HXMT x-ray telescope have made a direct measurement of the strongest magnetic field in the known universe. The magnetic field belongs to a magnetar currently in the process of cannibalizing an orbiting companion.

Even more pictures from James Webb Space Telescope, China’s planning a mission to Neptune, SpaceX’s Booster 7 suffers from an explosion, black holes are messy eaters, going under Europa’s ice crust and more.

Will we discover simple life somewhere? Maybe on Enceladus or Europa in our Solar System, or further away on an exoplanet? As we get more proficient at exploring our Solar System and studying exoplanets, the prospect of finding some simple life is moving out of the creative realm of science fiction and into concrete mission planning.
As the hopeful day of discovery draws nearer, it’s a good time to ask: what might this potential life look like?

After the ‘big reveal’ earlier this week of the James Webb Space Telescope’s first full color images and spectra of the universe, the science team has now released data from closer to home. One stunning shot includes Jupiter and its moons, and there are also data from several asteroids. These latest data are actually just engineering images, designed to test JWST’s ability to track solar system targets, as well as test out how the team can produce images from the data. The quality and detail in these test images have excited the mission scientists.

Living and working in space for extended periods of time presents a number of challenges. These include radiation, as locations beyond Earth’s protective magnetosphere are exposed to greater levels of solar and cosmic rays. There’s also the need for self-sufficiency since Lunar or Martian bases are too far to rely on regular resupply missions like the International Space Station (ISS). Last, there’s the issue of low gravity, which is especially pressing for long-term missions and habitats beyond Earth. If humanity’s future truly lies in space, we must devise solutions to this issue in advance.
A popular idea is to create rotating habitats in space that simulate artificial gravity, like the Pinwheel Station or the O’Neill Cylinder. Another proposal by a team of Japanese researchers calls for something bolder: a rotating habitat on the Moon! On July 5th, representatives from Kyoto University and the Kajima Corporation (one of the oldest and largest construction companies in Japan) announced that they would be partnering to conduct a study on this concept and how it could make humanity’s plans for living on the Moon and Mars a reality!

A team of astronomers have used the ALMA telescope to find a slowly-rotating galaxy in the early universe. That galaxy is the youngest ever found with a measured rotation, and it’s much slower than present-day galaxies.

People often seem surprised when they learn that NASA doesn’t just look out to the other planets, stars, and galaxies. It’s also an agency that studies our own home planet—from space! And why not? Earth is part of the solar system, too. So, to that end, there’s a new Earth studies mission called EMIT on its way to the International Space Station. It’s designed to track dust as it moves from one place to another on our planet through through our atmosphere.
The official name of the mission is the Earth Surface Mineral Dust Source Investigation (EMIT, for short). It will use a high-tech imaging spectrometer to study dust around the globe over the next year.

On the morning of Tuesday, July 12th, the world was treated to the first images captured by the James Webb Space Telescope – the most detailed images of the cosmos taken by the most powerful telescope ever! These featured familiar features from our galaxy, including updated images of the Carina Nebula, a nebula surrounding a stellar remnant (the Southern Ring), a collection of merging galaxies (Stephans Quintet), an exoplanet (WASP 96b), and a deep field image showing thousands of galaxies and gravitational lenses (SMACS 0723).
In anticipation of these images being released, a helpful space exploration ambassador shared a map that shows where these objects are located within (or in relation to) the Milky Way. The map was uploaded to the Reddit group Space on July 10th (two days before image release day) and is the work of data scientist Tony Rice (user name u/rtphokie). Rice is an information security engineer for a telecommunications company and a Solar System Ambassador with NASA’s Jet Propulsion Laboratory.

What happens when a star wanders too close to a supermassive black hole? The obvious story is that it gets sucked in, never to be seen again. Some of its material gets superheated on the way in and that gives off huge amounts of radiation—usually X-rays. That’s not a wrong explanation, just incomplete. There’s more to the story, thanks to a team of astronomers at the University of California at Berkeley. They used a specialized spectrograph at Lick Observatory to study a tidal disruption event. That’s where a star encountered a black hole. What they found was surprising.

This is it! Today, people worldwide were treated to the first images acquired by James Webb! After years of delays, we are finally seeing the sharpest images of the Universe taken by the most powerful telescope ever deployed. The world was given a sneak peek yesterday when President Biden, VP Kamala Harris, NASA Administrator Bill Nelson, and other NASA officials released the deepest and sharpest infrared image of the Universe to date. But at 10:30 Eastern (07:30 Pacific), all the remaining first images were released!
