That’s no moon! Scientists doubt proposed detection of the 1st exomoons
Scientists aren't sure whether humanity really detected moons outside the solar system.
If Our Part of the Universe is Less Dense, Would That Explain the Hubble Tension?
In the 1920s, Edwin Hubble and Georges Lemaitre made a startling discovery that forever changed our perception of the Universe. Upon observing galaxies beyond the Milky Way and measuring their spectra, they determined that the Universe was expanding. By the 1990s, with the help of the Hubble Space Telescope, scientists took the deepest images of the Universe to date and made another startling discovery: the rate of expansion is speeding up! This parameter, denoted by Lambda, is integral to the accepted model of cosmology, known as the Lambda Cold Dark Matter (LCDM) model.
'Dark force' theory could solve 2 open cosmic mysteries
A new theory suggests the universe's most mysterious and dominant form of matter could exert a "dark force."
Wild new NASA plasma tech reduces drag during hypersonic flight

All black holes feast chaotically, no matter how hungry they are
A fresh understanding of how black holes eat offers a new way to estimate their masses.
Did the Last Great Galactic Merger Create the Milky Way's Bar?
The Milky Way is a spiral galaxy. More specifically, it is a barred spiral galaxy, meaning that within its central region, there is a bar shape off of which the spirals emanate. About two-thirds of spiral galaxies are barred spirals, and astronomers have thought this difference is just a variance in how density waves cluster stars in a galaxy. But a new study suggests that the bar of the Milky Way may have been caused by an ancient collision with another galaxy.
A Star Near the Center of the Milky Way is a Visitor from Beyond
There’s an alien red giant star orbiting in the center of our galaxy. It’s called S0-6 and has chemical fingerprints from its birthplace far outside the Milky Way. This ancient star is spiraling slowly in toward the supermassive black hole Sagittarius A* (Sgr A*) at the heart of the Milky Way. Eventually, it could get drawn into the black hole and destroyed after traveling for tens of thousands of years to get there.
Halley's Comet begins its 38-year journey back toward Earth tonight

The International Space Station Celebrates 25 Years in Space
NASA recently celebrated the 25th anniversary of the International Space Station (ISS) with a space-to-Earth call between the 7-person Expedition 70 crew and outgoing NASA Associate Administrator, Bob Cabana, and ISS Program Manager, Joel Montalbano. On December 6, 1998, the U.S.-built Unity module and the Russian-built Zarya module were mated in the Space Shuttle Endeavour cargo bay, as Endeavour was responsible for launching Unity into orbit that same day, with Zarya having waited in orbit after being launched on November 20 from Kazakhstan.
