These may have been the strongest auroras in 500 years

(Evan Boyce)

This month's ramped-up auroras may have been even more remarkable than we thought. The auroral displays that wowed observers around the world two weekends ago, including folks as far south as Florida in the U.S. and Ladakh in northern India, may have been among the strongest such light shows since record-keeping began.

Scientists find where matter 'waterfalls' into black holes

(Robert Lea)

Scientists have confirmed, for the first time, that the very fabric of spacetime takes a "final plunge" at the edge of a black hole. The observation of this plunging region around black holes was made by astrophysicists at Oxford University Physics, and helps validate a key prediction of Albert Einstein's 1915 theory of gravity: general relativity.

What did our ancestors think when they looked up at the night sky? All cultures ascribed special meaning to the sun and the moon, but what about the pearly band of light and shadow we call the Milky Way?

1st Black astronaut candidate exults after suborbital launch

(Blue Origin)

Ed Dwight got to live out his long-delayed spaceflight dream over the weekend - and set a record in the process. In 1961, President John F. Kennedy selected Dwight to train at the U.S. Air Force's Aerospace Research Pilot School. ARPS was widely regarded as a conduit into NASA's astronaut corps at the time, so the pick made Dwight the United States' first Black astronaut candidate. He never moved beyond "candidate" status, however: Though Dwight completed his ARPS training and the Air Force recommended him for the astronaut corps, NASA didn't choose him.

New Hubble Telescope image reveals infant star's sparkle

(NASA, ESA, G. Duchene (Universite de Grenoble I); Image Processing: Gladys Kober (NASA/Catholic University of America))

Have you ever wondered what our sun looked like when it was young? Although we know the sun to be an unchanging, and even predictable source, of light in our skies, its youthful version some 4.6 billion years ago was quite active. During those formative years, our star spewed solar flares every week or so, despite shining only about a third as bright as it does now. We can't go back in time to witness these transformative events of course - but, thanks to NASA's Hubble Space Telescope, we now have a glimpse into similarly young, sun-like stars emerging elsewhere in the universe.

SpaceX fuels up Starship ahead of 4th test flight

(SpaceX)

SpaceX just fueled up its giant Starship rocket, checking another box ahead of the vehicle's fourth test flight. The company performed a "wet dress rehearsal" with Starship at its Starbase site in South Texas today (May 20), filling both of the vehicle's stages with supercold liquid oxygen and liquid methane in a key prelaunch test.

Rover's Mars sample may contain evidence of ancient life

(NASA/JPL-Caltech/ASU/MSSS/Ken Farley)

The lead scientist for NASA's Perseverance Mars rover is excited about material that has been stored in the rover's sample tubes, both dropped on the surface of Mars and contained within the rover itself while wheeling about within Jezero Crater. Given the samples of Mars that Perseverance has collected so far, could one of those specimens be what the rover was sent to look for in the first place: evidence of past microbial life on the Red Planet?

What did Noa see in 'Kingdom of the Planet of the Apes?'

(20th Century Studios)

Don't monkey around: The biggest reason we watch the "Planet of the Apes" movies is for the chance to see ape astronauts in NASA spacesuits once more! And that actually might be creeping closer to reality, if you believe some of the foreshadowing hints in director Wes Ball's new "Kingdom of the Planet of the Apes." Online theorists, armchair screenwriters and sci-fi speculators are going bananas over the prospect of the franchise launching back to the stars.

Blue Origin launches 1st crew since August 2022

(Blue Origin)

Blue Origin's nearly two-year human spaceflight drought is over. Jeff Bezos' aerospace company launched its NS-25 mission today (May 19), sending six people - including the United States' first-ever Black astronaut candidate -- on a brief trip to suborbital space aboard its New Shepard rocket-capsule combo.

This Week In Space: Episode 111 - The Big Glass Wars

(TWiS)

On Episode 111 of This Week In Space, Rod and Tariq talk with Dr. John Mulchaey, Director of the Carnegie Observatories, about the threat to completing two new giant astronomical observatories. Welcome to the Big Glass Wars! That's right, just when you thought you'd heard it all, turns out there's hot competition among a few countries to stay on the cutting edge of optical astronomy, and to do that, you need a great big hunk of glass to gather light from distant galaxies and stellar systems.

Bright green fireball lights up the skies over Portugal

(ESA/PDO/AMS82 - AllSky7)

The meteor was confirmed by European Space Agency (ESA), who caught the fireball with its cameras in Cáceres, Spain, at 6:46 p.m. EDT (22:46 UTC) on Saturday (May 18). The ESA confirmed that the fireball was a piece of a comet that rocketed over Spain and Portugal, traveling at around 100,000 miles per hour, or about 65 times as fast as the top speed of a Lockheed Martin F-16 jet fighter. The ESA added that the meteor likely burned up over the Atlantic Ocean at an altitude of around 38 miles (60 kilometers) over Earth. Social media users took to X, Facebook, and Reddit by the thousands to discuss the bright fireball and share stunning images and videos.

PREFIRE ready to unlock mysteries of Earth's poles

(NASA/JPL-Caltech)

NASA is preparing to launch its latest climate science mission, the Polar Radiant Energy in the Far-Infrared Experiment (PREFIRE), which aims to capture brand new data on how heat is lost to space from Earth's polar regions. PREFIRE consists of a pair of cubesats that will launch separately into near-polar orbits. The first, "Ready, Aim, PREFIRE," is set to launch no earlier than (NET) May 22, on a Rocket Lab Electron rocket from Pad B at the company's Launch Complex 1, in Māhia, New Zealand. The second cubesat, "PREFIRE and ICE," will launch a few days later.

Pulsed plasma rocket aims to get to Mars in 2 months

(Howe Industries)

An innovative rocket system could revolutionize future deep space missions to Mars, reducing travel time to the Red Planet to just a few months. The goal of landing humans on Mars has presented a myriad of challenges, including the need to quickly transport large payloads to and from the distant planet, which, depending on the positions of Earth and Mars, would take almost two years for a round trip using current propulsion technology.

Budget binoculars 2024: Cheap but high-quality models

(Tantse Walter)

The best budget binoculars make hobbies like astronomy and birdwatching more accessible because, let's face it, investing in optics can get expensive quickly. Not everyone can afford to buy top-of-the-line products, but that doesn't mean we should be deprived of hobbies and experiences. Inexpensive binoculars can be a more economical solution for those who want to use them occasionally.

We're about to discover how "the world went quiet" in A Quiet Place: Day One, a prequel that depicts the sudden apocalypse on a much larger scale. With the critical and financial success of both A Quiet Place and A Quiet Place Part II, it should come as no surprise that we're getting more.

'Star Wars: The Phantom Menace' at 25

(20th Century Fox)

Yippee! "Star Wars: The Phantom Menace" blows out the candles on its 25th anniversary birthday cake yesterday. After taking in a screening during its short return to theaters for Star Wars Day week, we can honestly say that this polarizing film still has its problems but honestly elicits enough thrills to warrant a repeat viewing, if only to hear John Williams sweeping musical score and see Ray Park's acrobatic Darth Maul twirl his double-bladed lightsaber while seething with palpable hatred toward the gallant Jedi Knights.
