Webb NIRISS Instrument has Gone Offline

The JWST is having a problem. One of its instruments, the Near Infrared Imager and Slitless Spectrograph (NIRISS,) has gone offline. The NIRISS performs spectroscopy on exoplanet atmospheres, among other things. It’s been offline since Sunday. January 15th due to a communications error. The internal communications...

Lucy Adds Another Asteroid to its Flyby List

In October 2021, NASA launched its ambitious Lucy mission. Its targets are asteroids, two in the main belt and eight Jupiter trojans, which orbit the Sun in the same path as Jupiter. The mission is named after early hominin fossils (Australopithecus afarensis,) and the name pays homage to the idea that asteroids are fossils from the Solar System’s early...

Astronomers Pin Down the Age of the Most Distant Galaxy: Seen 367 Million Years After the Big Bang

Staring off into the ancient past with a $10 billion space telescope, hoping to find extraordinarily faint signals from the earliest galaxies, might seem like a forlorn task. But it’s only forlorn if we don’t find any. Now that the James Webb Space Telescope has found those signals, the exercise has moved from forlorn to hopeful. But only if...

Perseverance Takes a Selfie to Show off Some of its Samples

One of the main jobs for the Perseverance Mars rover past few weeks has been collecting carefully selected samples of Mars rock and soil. These samples have been placed and sealed in special sample tubes and left in well-identified places so that a future sample return mission can collect them and bring the Martian samples back to Earth. Perseverance...

There's a Crater on Mars That Looks Like a Bear

Facial pareidolia is the human tendency or illusion of seeing facial structures in an everyday objects – such as seeing the “man in the Moon,” or the face of Jesus on a piece of toast. But here’s a newly found crater on Mars that might be a case of ‘bear-adoilia.’ There’s no denying, the crater looks like a bear’s face. We’ve seen some...

According to Simulations, the Milky Way is One in a Million

Humanity is in a back-and-forth relationship with nature. First, we thought we were at the center of everything, with the Sun and the entire cosmos rotating around our little planet. We eventually realized that wasn’t true. Over the centuries, we’ve found that though Earth and life might be rare, our Sun is pretty normal, our Solar System is relatively...

Study Shows How Cells Could Help Artemis Astronauts Exercise

In 2033, NASA and China plan to send the first crewed missions to Mars. These missions will launch every two years when Earth and Mars are at the closest points in their orbits (Mars Opposition). It will take these missions six to nine months to reach the Red Planet using conventional technology. This means that astronauts could spend up to a year and...

Spectacular Images of the Rare ‘Green Comet’ Gracing Our Skies

A rare ‘green’ comet is passing through our Solar System and astrophotographers have been out capturing photos. While this comet, named C/2022 E3 (ZTF) is not yet visible yet to the naked eye, it could be when it makes its closest approach to Earth on February 1, but you’ll likely need to be in a very dark site. As of now, you’ll need a telescope or...

Physicist encourages continuing the search for life in Venus’ atmosphere

In a recent paper accepted to Contemporary Physics, a physicist from Imperial College London uses past missions and recent findings to encourage the importance of searching for life in the atmosphere of the solar system’s most inhospitable planet, Venus. This comes as a 2020 announcement claimed to have discovered the presence of phosphine in Venus’...

Dust is Hiding how Powerful Quasars Really are

In the 1970s, astronomers discovered that the persistent radio source at the center of our galaxy was a supermassive black hole (SMBH). Today, this gravitational behemoth is known as Sagittarius A* and has a mass roughly 4 million times that of the Sun. Since then, surveys have shown that SMBHs reside at the center of most massive galaxies and play...
