Could aliens ever visit Earth? An aerospace scientist unpacks the challenges of interstellar spaceflight

On May 22, 2026, the Pentagon released a second batch of previously classified photos and videos showing what appear to be unexplained flying objects. These file dumps were the culmination of a process that was set in motion back in July 2023, when a group of government whistleblowers testified before Congress that the U.S. government was secretly in possession of extraterrestrial spacecraft and suspected alien body parts.

May 27, 1933: Arcturus lights up the World’s Fair

When organizers of the 1933 World’s Fair in Chicago wanted a splashy and futuristic way to kick things off on opening night, astronomer Edwin Frost of Yerkes Observatory had an idea: Turn on the lights with power generated by starlight. Thought to be located 40 light-years away, Arcturus was chosen for the poetic symbolism ofContinue reading “May 27, 1933: Arcturus lights up the World’s Fair” The post May 27, 1933: Arcturus lights up the World’s Continue ReadingMay 27, 1933: Arcturus lights up the World’s Fair

‘One of the great unresolved embarrassments of physics’: It’s been 340 years since Newton and scientists still haven’t solved the secret of gravity

Big G is the oldest fundamental constant in physics and remains the least clearly defined. One scientist has spent a decade attempting to crack the mystery of the gravitational constant, and it all came down to the opening of a single envelope. Continue Reading‘One of the great unresolved embarrassments of physics’: It’s been 340 years since Newton and scientists still haven’t solved the secret of gravity

NASA TESS Reveals Epic All-Sky Map of Distant Worlds

You’re on a camping trip with your family and your parents tell you to turn off all the lights. But, of course, your little brother wants to shine his flashlight directly at the sky saying aliens will see it. You finally get him to shut off his flashlight, and you give your eyes a few minutes to adjust to the darkness. As they do, more and more stars begin to appear in the night sky that were initially hidden beneath the glare of your (loser) brother’s flashlight. As the stars get brighter and increase in number, you start firing off a slew of questions in your head: How far away are they? Are there planets around them? What kinds of life are on those planets?

NASA outlines nearly $1 billion investment into initial Moon Base missions

The agency announced that two companies developing lunar terrain vehicles (LTVs), Astrolab and Lunar Outpost, would each be receiving Continue ReadingNASA outlines nearly $1 billion investment into initial Moon Base missions

Astronomers Observe the Most Chemically Primitive Galaxy in the Early Universe

An international team led by Associate Professor Kimihiko Nakajima of Kanazawa University has captured a rare look at the early universe. Using the James Webb Space Telescope (JWST) and the power of gravitational lensing, the team achieved a definitive characterization of LAP1-B, an ultra-faint galaxy from 13 billion years ago.

Artemis moon base will cover ‘hundreds of square miles’ with hopping drones and new lunar rovers, NASA says

NASA envisions its moon base covering hundreds of square miles, and hopping scout drones may mark the facility’s perimeter. The agency just awarded $1 billion in contracts to get the ball rolling. Continue ReadingArtemis moon base will cover ‘hundreds of square miles’ with hopping drones and new lunar rovers, NASA says
