The Pentagon released a new tranche of UFO files on Friday (May 8). Among the documents are nearly 30 videos, which feature a range of intriguing objects.
The Department of Defense has released a fresh batch of images and transcripts relating to reports of unidentified anomalous phenomena, formerly known as UFOs, including pictures and descriptions from NASA's Apollo missions to the moon.
Powerful bright blue cosmic explosions called Luminous Fast Blue Optical Transients could be caused when a black hole or neutron star slams into the universe's hottest class of star.

What sci-fi gets right (and mostly wrong) about all the ways that space wants to kill you.

Black holes live forever, at least according to general relativity. Once material crosses a black hole's event horizon, it is trapped forever. Until the last day of cosmic time. But we know that isn't true. General relativity is a classical model. It doesn't take into account the fuzzy, indeterminate nature of the quantum. We don't have a complete and consistent theory of quantum gravity, but we do have some understanding of quantum black holes.
Blue Origin continues putting its first lunar lander through its paces, testing the spacecraft at NASA centers across the nation to prepare it for its upcoming mission to the moon.
We must fight the Lylat Wars... again.
NASA's Artemis 2 Orion spacecraft rests after its flight around the moon, charred from the return to Earth.
Aerospace engineers have to consider numerous factors when designing a spacecraft, but one that comes up more and more often is the need to design against Micro-Meteoroids and Orbital Debris (MMOD). While most designers understand the threat, designing structural solutions capable of withstanding the hypervelocity impacts these undercontrolled pieces of material can cause can take a significant bite out of a mission’s mass budget. A new paper from Binkal Kumar Sharma of the University of Bremen and Harshitha Baskar, an independent researcher, provides a detailed review of cutting-edge options for defending against those deadly particles.
Forget apps — May's bright stars and classic spring constellations make this the perfect time to learn the sky the old-fashioned way, one star-hop at a time.
It would appear we now have 10,091 candidate exoplanets to go through and confirm.
SpaceX just took a big step toward its next Starship test flight, firing up all 33 engines of the vehicle's Super Heavy on the pad in Texas.
The Artemis 2 astronauts saw several impact flashes on the moon during their epic April 6 flyby, observations that have excited scientists and mission planners alike.
Jupiter, shining high the western dusk, inches down day toward brighter Venus. Venus, meanwhile, creeps toward the horntip stars of Taurus and stands between them on May 13th.

The imminent lunar impact of a SpaceX Falcon 9 rocket booster highlights the growing amount of space debris near the Moon.
When researchers look up at the sky and wonder if we’re not alone, they also realize the origins of life here on Earth might hold the key to finding out. The chaotic chemical soup of our early world eventually led to the staggering complexity of modern life, but how exactly did it start? Proteins were one of the key ingredients in the early years, but we’re still only just discovering how these marvels of modern biology first managed to fold, function, and survive. A new review paper, The borderlands of foldability: lessons from simplified proteins, published recently in Trends in Chemistry, showcases how scientists are attempting to answer this question - by researching “simplified proteins”.
The Universe is an unfathomably large and ancient place. It began with a giant explosion roughly 14 billion years ago (the Big Bang) and has been in a state of expansion ever since. Based on current estimates, there are more than 2 trillion galaxies in the "observable Universe," some with as many as a trillion stars each. Within our galaxy alone, there are between 100 and 400 billion stars and 100 to 160 billion planets. And according to every bit of scientific evidence available, the ingredients for life are everything in abundance.
