In July of 1969, humanity took our first steps on the surface of another world: the Moon. This was the crowning achievement of NASA and the space program in the 1960s, representing a global victory for science and human achievement....
In the very early Universe, there were tremendous numbers of quarks, leptons, antiquarks, and antileptons of all species. After only a tiny fraction-of-a-second has elapsed since the hot Big Bang, most of these matter-antimatter pairs annihilate away, leaving a very...
The SphereX (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) mission, slated for launch on February 28. 2025, is designed to map out hundreds of millions of galaxies over the entire sky in an attempt...
This selection of the Andromeda galaxy comes courtesy of the largest photomosaic ever assembled with Hubble Space Telescope data. There’s an enormous wealth of astronomical data found within the image: far more than is readily visible to the human eye....
The full-field image of MACS J0717.5+3745 shows many thousands of galaxies in four separate sub-clusters within the large cluster. The blue contours show the inferred mass distribution from the gravitational lensing effects on background objects. Not shown in this diagram...
In February of 2025, noted anti-vaccine, anti-fluoride, and anti-GMO crusader Robert F. Kennedy, Jr., despite the objection of qualified scientists and medical professionals, was sworn in as the director of Health and Human Services in the United States. (Credit: Associated...
If a massive asteroid, similar in size to 2024 YR4 or the body that created the Tunguska Event, were to stream through our atmosphere and collide with our planet, it could potentially level an entire city, causing trillions of dollars...
This illustration shows a star, an orbiting exoplanet, and a cloud (or tail) of debris that emanates off of the exoplanet and obscures a fraction of the parent star’s light. At close enough distances and hot enough temperatures, it won’t...
Prior to the pioneering 2025 work that discovered the Bullseye galaxy, showcased here, no galaxy had more than three concentric rings ever discovered within it. The Bullseye galaxy has at least 9, and potentially more that have faded away, due...
Here in our own Solar System, we have at least three notable large, terrestrial-sized bodies with impressive lunar systems of their own: the Earth-Moon system, the Mars-Phobos-Deimos system, and the Plutonian planetary system. Pluto, interestingly, is orbited by Charon, which...
