A New Instrument is Going to the ISS to Study the Climate Impact of Dust in Earth’s Upper Atmosphere

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.

Here are the Locations in the sky for the First JWST Images

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).

A Star Came too Close to a Black Hole and was Torn Apart. Surprisingly Little Actually Went In

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.

Perseverance is Searching for the Perfect Landing Spot for the Upcoming Sample Return Mission

NASA’s car-sized Perseverance (Percy) Mars rover has been had at work carrying out its science campaign in Jezero Crater on the Red Planet, but it’s equally been busy scouting for sites for NASA’s planned Mars Sample Return (MSR) mission, which is a joint mission with the European Space Agency. One of the many tasks for Percy has been to collect sample tubes that MSR will eventually return to Earth for further analysis, having collected its ninth sample on July 6. This most recent sample is especially intriguing as it’s the first taken from the Jezero’s delta itself, which is believed to be one of the most ideal locations to search for past life on the Red Planet.

Dusty Dark Galaxies in the Early Universe Revealed in Various Wavelengths

Well, this is the week for distant galaxies, isn’t it? Not only has JWST revealed some of the most distant ones ever seen in infrared, but other observatories are studying them, too. Astronomers at the Cosmic Dawn Center in Copenhagen recently discovered several interesting ones in the early Universe. However, they had to get through clouds of dust to do it. Their observations revealed several interesting characteristics of objects that existed when the Universe was only a tenth of its current age.

China’s Tianwen-1 has Imaged the Entire Surface of Mars, Completing its Primary Mission

After exploring Mars for more than a year, China’s Tianwen-1 space probe has successfully taken images covering the entire Red Planet, China’s National Space Administration (CNSA) announced on June 29. Tianwen-1, which translates to “quest for heavenly truth”, consists of six separate spacecraft: an orbiter, two deployable cameras, lander, remote camera, and Zhurong rover. The images in question were taken by the orbiter while circling Mars 1,344 times, capturing images of the Red Planet from every angle while Zhurong explored the surface. in the statement, CNSA said the probe has now completed all of its tasks, which included taking medium-resolution images covering the entire planet.

Behold, the James Webb Space Telescope’s First Image!

On December 25th, 2021, the James Webb Space Telescope launched from Cape Canaveral bound for space. After many years of delays, retesting, and cost overruns, the next-generation observatory made it to orbit without any hiccups or complications. What followed was several weeks of deployment as Webb unfolded its arms, sunshield, primary mirror (consisting of eighteen gold-coated beryllium segments), and secondary mirror. By late January, the space telescope had flown to the Sun-Earth L2 Lagrange Point, where it will remain for the entirety of its mission.

A Swarm of Swimming Robots to Search for Life Under the Ice on Europa

When Galileo pointed his telescope at Jupiter 400 years ago, he saw three blobs of light around the giant planet, which he at first thought were fixed stars. He kept looking, and eventually, he spotted a fourth blob and noticed the blobs were moving. Galileo’s discovery of objects orbiting something other than Earth—which we call the Galilean moons in his honour—struck a blow to the Ptolemaic (geocentric) worldview of the time.

China is Considering a Nuclear-Powered Mission to Neptune

One look at the Planetary Decadal Survey for 2023 – 2032, and you will see some bold and cutting-edge mission proposals for the coming decade. Examples include a Uranus Orbiter and Probe (UOP) that would study Uranus’ interior, atmosphere, magnetosphere, satellites, and rings; and an Enceladus orbiter and surface lander to study the active plumes emanating from Enceladus’ southern polar region. Not to be outdone, China is also considering a nuclear-powered Neptune Explorer to explore the ice giant, its largest moon (Triton), and its other satellites and rings.

The Most Threatening Asteroid Just got Downgraded to “Harmless”. No Impact in 2052

It’s comforting to know that there are people who are literally paid to watch the night sky to ensure that at least we’ll be informed if an asteroid will hit the Earth. Technology and near-Earth surveys have become advanced enough that the likelihood of a planet-killer-sized asteroid coming out of nowhere, as is so prevalent in modern media depictions, is extremely unlikely. Even smaller ones, which would only wipe out a city or part of a continent, get enough attention to tell if they pose a threat or not. And in advance of Asteroid Day 2022, which happened on June 30th, ESA is proud to announce they were able to remove one of the most threatening asteroids from their potential impact list.

When did the Sun Blow Away the Solar Nebula?

The story of our solar system’s origin is pretty well known. It goes like this: the Sun began as a protostar in its “solar nebula” over 4.5 billion years ago. Over the course of several million years, the planets emerged from this nebula and it dissipated away. Of course, the devil is in the details. For example, exactly how long did the protoplanetary disk that gave birth to the planets last? A recent paper submitted to the Journal of Geophysical Research takes a closer look at the planetary birth crèche. In particular, it shows how the magnetism of meteorites helps tell the story.

Snooping on Alien Messages Passing Through the Solar System

Researchers at Penn State University have studied a new technique that could use a star’s ability to focus and magnify communications which could be passing through our own solar system, and has been accepted for publication in The Astronomical Journal and was part of a graduate course at Penn State covering the Search for Extraterrestrial Intelligence (SETI. The study describes our Sun as potentially acting as a kind of node as part of an interstellar communication network involving probes or relays near our Sun, acting like cellular telephone towers in space.

Many Astronauts Never Recover all of their Bone Density after Returning to Earth

In his book, Endurance, astronaut Scott Kelly described the arduous task of readjusting to life on Earth after spending a year in space. As part of NASA’s Twins Study, Kelly lived and worked aboard the International Space Station (ISS) while his identical twin (astronaut Mark Kelly) remained on Earth. While the results of this study revealed how prolonged exposure to microgravity could lead to all manner of physiological changes, the long and painful recovery Kelly described in his book painted a much more personal and candid picture.

Supermassive Black Holes Formed Directly out of Enormous Streams of Cold gas

At the edge of known space are quasars. They are powerful cosmic engines capable of creating intense beams of light across billions of light years. And they are powered by supermassive black holes (SMBHs). Most galaxies have a SMBH, including our own galaxy, but for quasars to be so powerful their SMBHs must have become very large very quickly. We’re still learning just how they formed. We’ve long thought their formation involved a special set of circumstances, but a new study shows that early quasars could have formed purely from cold dark gas.

Engineers Build a gun That can Fire Projectiles at 10 km/s, Simulating High-Speed Space Debris Impacts

According to the ESA’s Space Debris Office (SDO), there are about 31,630 debris objects in orbit that are regularly tracked by space surveillance networks. However, this only accounts for the larger objects and doesn’t include the (literally) millions of tiny bits of “space junk” that pollute Low Earth Orbit (LEO). According to the SDO, this includes an estimated 36,500 objects greater than 10 cm in diameter (~4 inches), 1 million space debris objects measuring between 1 cm to 10 cm (0.4 to 4 inches), and 130 million space debris objects measuring between 1 mm to 1 cm.
