Each year in mid-August, Earth plows through the debris stream of an enormous comet, creating the Perseids. 2023's show will be magnificent!
The view from beyond Pluto is far enough from Earth that we can see the stars shift. NASA’s New Horizons, humanity’s first spacecraft to encounter Pluto, is more than 4.3 billion […]
Gravitation, all on its own, can reveal what's present in the cosmos like nothing else.
There will always be "wolf-criers" whose claims wither under scrutiny. But aliens are certainly out there, if science dares to find them.
NASA has finally chosen which flagship mission, like Hubble and JWST, will launch in ~2040. Detecting alien life is now a reachable goal.
It likely isn’t the rare occurrence we once thought it was. In our Solar System, there’s one overwhelming source of mass that all the planets orbit around: our Sun. Each planet […]
Our Universe requires dark matter in order to make sense of things, astrophysically. Could massive photons do the trick?
With a telescope at just the right distance from the Sun, we could use its gravity to enhance and magnify a potentially inhabited planet.
We just observed the first ‘lunar formation’ in an exoplanetary system. This one image, above, is the first to show moons actively forming around a planet. This colourful image shows […]
A theoretical view of a distant world so far from our Sun that our Solar System appears barely brighter than the remaining stars in the sky. ( Caltech/R. Hurt (IPAC)) Pluto […]
Ingenuity is remarkable. But these 5 exploration ideas are revolutionary. Telescopes are our initial tools for revealing and studying foreign worlds. Hubble images of Mars, particularly around the regions with […]
It’s one of only five spacecraft that will exit the Solar System, and the only one we have a chance to aim at another star. Of all the spacecraft ever launched, […]
The definitive answer requires better, unbiased data. Despite all the advances that have occurred in human history, one extraordinary puzzle still remains right in our own backyard: we aren’t sure how […]
The theory could resolve some unanswered questions.
As long as it remains operational, we’ll have a chance to conduct groundbreaking science with it. In the history of spaceflight, only five spacecraft ever launched by humanity possess enough energy […]
It’s not just for Earth-like planets around Sun-like stars. Not even close. Shortly after Earth first formed first formed, life quickly took hold, thriving ever since. Both reflected sunlight on a […]
Halley’s comet only visits every ~76 years, but its meteors arrive twice each year. The most famous comet of all — Halley’s comet — returns to our inner Solar System every ~76 years. Halley’s comet […]
The same (former) NASA engineer who previously claimed to violate Newton's laws is now claiming to have made a warp bubble. He didn't.
Already 14 billion miles from the Sun, Voyager 1 is speeding away at 38,000 mph.
NASA’s New Horizons is the most distant technologically advanced observatory ever. And that makes all the difference. When you look at an object that’s very distant from you, how well […]
