Should We Build a Nature Reserve on Mars?

There are 8 billion of us now. The UN says when the population peaks around the year 2100, there’ll be 11 billion human souls. Our population growth is colliding with the natural world on a greater scale than ever, and we’re losing between 200 and 2,000 species each year, according to the World Wildlife Federation.

NASA Releases a Stunning New Supercut of the Artemis I Launch

NASA just released a new supercut of high-resolution video from the Artemis I launch on November 16, 2022. Much of the footage is from cameras attached to the rocket itself, allowing everyone to ride along from engine ignition to the separation of the Orion capsule as it begins its journey to the Moon.

Two Great Globular Clusters Seen by Hubble: Pismis 26 and Ruprecht 106

If you like shiny things, some of the most gorgeous objects in space are globular clusters, with their bright, densely packed collections of gleaming stars. And if you like globular clusters, you’re in luck: two different Hubble images of globular clusters were featured this week by NASA and ESA.

What if we’re truly alone?

At least once, you’ve looked up at the night sky and asked the same longstanding question we’ve all asked at least once, “Are we alone?” With all those points of light out there, we can’t be the only intelligent beings in the universe, right? There must be at least one technological civilization aside from us in the great vastness that we call the cosmos.

Quasars Produce Giant Jets That Focus Like Lasers. Why They Focus is Still a Mystery, but it’s not Coming From the Galaxy Itself

New technologies bring new astronomical insights, which is especially satisfying when they help answer debates that have been ongoing for decades. One of those debates is why exactly the plasma emitted from pulsars “collimates” or is brought together in a narrow beam. While it doesn’t provide a definitive answer to that question, a new paper from an international group of scientists points to a potential solution, but it will require even more advanced technologies.

Astronomers Directly Image a Jupiter-Sized Planet Orbiting a Sunlike Star

According to the most widely-accepted theory, planetary systems form from large clouds of dust and gas that form disks around young stars. Over time, these disks accrete to create planets of varying size, composition, and distance from their parent star. In the past few decades, observations in the mid- and far-infrared wavelengths have led to the discovery of debris disks around young stars (less than 100 million years old). This has allowed astronomers to study planetary systems in their early history, providing new insight into how systems form and evolve.

Astronomers Detect the Faint Glow of Stars in Between Galaxies

Not all stars are members of galaxies. Some stars exist in the space between galaxies, though they didn’t form there. They’re called intra-group stars, and astronomers study them by observing their light, called intra-group light (IGL.)

The Technique for Detecting Meteors Could be Used to Find Dark Matter Particles Entering the Atmosphere

Researchers from Ohio State University have come up with a novel method to detect dark matter, based on existing meteor-detecting technology. By using ground-based radar to search for ionization trails, similar to those produced by meteors as they streak through the air, they hope to use the Earth’s atmosphere as a super-sized particle detector. The results of experiments using this technique would help researchers to narrow down the range of possible characteristics of dark matter particles.

The Second-Closest Supermassive Black Hole Might be in a Nearby Dwarf Galaxy

There’s a little galaxy in the Milky Way’s cosmic neighborhood called Leo 1. It’s a dwarf spheroidal that lies less than a million light-years away from us. Surprisingly, it has a supermassive black hole about the same mass as Sagittarius A* in our galaxy. That’s unusual in several ways, and astronomers want to know more about it.

Nature’s Ultra-Rare Isotopes Can’t Hide from this New Particle Accelerator

A new particle accelerator at Michigan State University is producing long-awaited results. It’s called the Facility for Rare Isotope Beams, and it was completed in January 2022. Researchers have published the first results from the linear accelerator in the journal Physics Review Letters.

Gaze Slack-jawed at the Haunting Beauty of Galaxy NGC 1566, Captured by JWST, Processed by Judy Schmidt

Here’s an absolutely stunning new view from the James Webb Space Telescope of a dusty spiral galaxy, NGC 1566. Amateur (but expert!) image editor Judy Schmidt took the raw data from JWST’s Mid-Infrared Instrument (MIRI) and teased out this eerie, spider-web-like view of this distant galaxy. The swirling and symmetrical arms are so full of dust that not many stars are visible.

Astronomers Spotted a Tiny Asteroid A Few Hours Before it Impacted the Earth, and Predicted Exactly Where and When it Would Crash

Humanity is getting better a planetary defense. At least from external threats from outer space. As long as they’re just dumb rocks that follow the laws of physics. And a group of extraordinary humans proved it last week when the planetary defense community jumped into action to accurately track and predict exactly where a relatively small meteor would fall on November 19th.

What’s Next for China’s Lunar Exploration Plans?

China is starting to become a force in space exploration. Its main focal point of lunar exploration has started bearing fruit, with several successes, including a sample return mission and the first-ever craft to land on the far side. So what’s next for the Lunar Exploration Program? Establishing a research base may be on the cards, but the country doesn’t just plan to stop at the Moon – they are looking far beyond.

Based on the JWST Controversy, NASA is re-Evaluating the way it Names Spacecraft

In 2015, the naming of the James Webb Space Telescope (JWST) became the subject of controversy when it was revealed that the namesake (NASA’s administrator between 1961 and 1968) was involved in the infamous “Lavender Scare.” This refers to the period in the late 1940s and early 50s when the U.S. State Department purged thousands of individuals from their positions due to allegations of homosexuality. In 2021, NASA Administrator Bill Nelson requested a formal and public report and tasked NASA’s Chief Historian Brian C. Odom with investigating the matter.

Many Clouds on Mars are Driven by Dust, not Water

One of the benefits of having a cluster of satellites orbiting another planet is that scientists can then analyze that planet’s weather. Sometimes in that process, they find patterns that are strikingly similar to those found on our home planet. That was the case recently when a group of scientists from ESA used data from Mars Express to analyze cloud formation on Mars. To no one’s surprise, dust seemed to be at the core of that formation. But the resultant clouds looked very much like those found here on Earth – in the tropics.

Air-Breathing ion Engines can Continuously Boost Spacecraft Anywhere There’s an Atmosphere

Staying in orbit can be challenging, at least for lower orbits that are more affected by Earth’s atmosphere. But, such orbits also come with advantages, such as better vantage points for new commercial operations such as Earth Observation and telecommunications connections. So there is an incentive for anyone who can figure out how to functionally keep a satellite in orbit at those lower altitudes for long periods. One of the best paths toward that goal seems to be an ion engine that takes in atmospheric particles and uses them for thrust. Now, a recently released paper explores potential use cases for such an engine and suggests a path toward their commercialization.

Subaru Telescope can now Analyze 2,400 Galaxies Simultaneously

First light is an exciting time for astronomers and engineers who help bring new telescopes up to speed. One of the most recent and significant first light milestones recently occurred at the Subaru Telescope in Hawai’i. Though it has been in operation since 2005, the National Astronomical Observatory of Japan’s (NAOJ) main telescope recently received an upgrade that will allow it to simultaneously observe 2400 astronomical objects at once over a patch of sky the size of several moons.
