Here are some recent space-related stories.

—Techcrunch: “NASA Picks Eric Schmidt’s Rocket Company for Mars Mission, Setting Up a Race with SpaceX“

Relativity Space — a rocket maker acquired by former Google executive chair Eric Schmidt last year after stumbling on the path to orbit — might just beat SpaceX to Mars. On Tuesday, NASA said it hired the company to build a spacecraft to house a suite of scientific instruments, launch it into space, and fly it to Mars. The structure of the contract is akin to the deals that NASA made with SpaceX to fly cargo to the International Space Station, or Firefly Aerospace to put a lander on the moon. The government agency handles the science, while the private company provides low-cost infrastructure.

—Universe Today: “Astronomers Want to Build a Swarm of Telescopes to Find LIFE“

Current plans for flagship telescopes in the 2040s are focused on answering a simple question – are we alone? Our best telescopes to date, such as the James Webb Space Telescope (JWST) have only given us tantalizing glimpses into the atmospheres or other worlds, but not enough to truly determine whether or not life as we know it exists there. Astronomers have been waiting for technology to catch up to their dreams of what is possible in terms of new types of telescopes, and recently the W.M. Keck Institute for Space Studies released a report detailing the Large Interferometer For Exoplanets (LIFE) mission, which they hope will help provide a definitive answer to that simple question.

—BBC Sky at Night: “The Pink Planet is So Weird, Astronomers Struggle to Define It. And They’ve Just Found It’s Covered in Salty Clouds“

There’s a pink planet, just a stone’s throw from Earth, that astronomers have been trying to decipher for over a decade. Known as the Pink Planet or, officially, GJ504b, this strange world orbits a Sun-like star 57 lightyears from Earth. Astronomers aren’t even sure if it’s a planet at all. About 25 times the mass of Jupiter, it’s so massive it’s on the boundary between giant planets and brown dwarfs (a type of failed star). But observations with the James Webb Space Telescope have revealed direct evidence for something rather strange at the Pink Planet: salty clouds.

Space Quote: Every Day is Disclosure Day

“There’s no effort to keep it secret. If we [get] a signal, it’s going to be out there. The next step is transparency.”

-Statement by Dr. Carol Oliver, as quoted in a Scientific American article titled, “What Disclosure Day Gets Wrong About the Search for Aliens.” Dr. Oliver is a professor of science communication and astrobiology at the University of New South Wales in Australia. She is also involved with the latest version of the SETI Post-Detection Protocols, which establishes procedures for astronomers who believe they have detected evidence of an extra-terrestrial civilization.

Twisted White House Humor Involving Aliens

The same White House that promised to share information on UFOs and potential alien visits is now spreading disinformation on non-citizens. Just go to aliens.gov and check it our for yourself.

When you go to the site you are hit with language like this:

Millions arrived under the cover of darkness and embedded themselves directly into our society.

Countless presidents, congressmen, and senior officials knew exactly what was happening.

But what you really have is a government page connected to ICE where you can turn in your neighbors. It sounds more like a twisted government playing off of the recent film Disclosure Day while generally insulting those Americans who were hoping this government could shed some light on UFOs.

Wired magazine also highlighted the flawed information on the website, noting:

One of the first things visitors to the site see is a counter labeled “encounters,” ostensibly indicating how many undocumented immigrants federal agents have arrested since Trump took office. The counter is fake. The starting number—3,129,580—is hand-typed into the website, and its upward motion is generated by a timer initiated by the visitor’s own browser, according to a WIRED analysis of the site’s code. The figure does not correspond to any enforcement total published by immigration authorities and is roughly seven times larger than the actual ICE arrest count since January 2025.

So again, what we have is a government promising transparency about UFO records only to mislead the public with a bait-and-switch page providing false information.

Is anyone really surprised that the public does not trust the government on such matters?

Pic of the Week: Galaxy M83

This week’s image is from the Chandra X-ray Observatory. It shows galaxy Messier 83 (M83), which is located approximately 15 million light-years from Earth. It is part of a study analyzing Chandra data from 2000 to 2014.

NASA provides more information on a recent study involving supernova remnants being studied by astronomers:

In the composite image, Messier 83, or M83, is shown to have a spiral structure, viewed straight on. At the center is a brilliant white and yellow pool of light. From that light, spiral arms of hot pink cloud corkscrew out in wide, sweeping arches. The galaxy is covered in a faint grey haze, and flecked with red, green, blue, white, and yellow dots.

Over a 14-year period from 2000 to 2014, astronomers pointed NASA’s X-ray observatory at the M83 galaxy. They discovered that about half of the X-ray sources believed to be supernova remnants, the aftermath of stellar explosions, were exhibiting dramatic changes in brightness. This result was entirely unexpected.

Those changes in brightness are highlighted in the timelapse videos. In each video, a series of static images flashes by, focused on one of the two X-ray sources once believed to be supernova remnants. In the videos, the X-ray sources appear as bright blue blobs with glowing cores. But in each image, taken months or years apart, the shapes change, as does the intensity of the blue color, and the brightness of the core. By presenting the substantively different images of the same objects one after another in quick succession, short timelapse videos are created.

The most likely explanation for the changes in brightness is that the team has uncovered a population of stellar survivors, stars that lived through an orbiting partner’s destruction in a supernova explosion. Material is being pulled from the surviving star onto the black hole or neutron star that formed in the supernova, a process known to cause rapid changes in X-ray brightness.
