If you had a clear western horizon, you had your shot at this view! On September 9, 2021, the Moon and Venus nearly overlapped. A simulated view of the post-sunset skies […]
And, at some point, did the Milky Way lose ours? There are some 400 billion objects flying through the Milky Way galaxy with enough mass that — if they were all made of […]
Just say no to artist’s illustrations. This is what the Universe actually looks like. The Universe we observe often surpasses our greatest imaginings. This 20-year time-lapse of stars near the center […]
A fairly old idea, but a really good one, is about to hit the store shelves.
Once science operations begin for James Webb, we’ll never look at the Universe the same way again. Here’s what everyone should know.
In a joint briefing at the 101st American Meteorological Society Annual Meeting, NASA and NOAA revealed 2020’s scorching climate data.
The first world that humans should inhabit beyond the Earth is the Moon, not Mars. Here’s why terraforming our lunar neighbor is so appealing.
An analysis of the gravitational wave data from black hole mergers show that the event horizon area, and entropy, always increases.
As early as we’ve been able to identify them, the youngest galaxies seem to have large supermassive black holes. Here’s how they were made.
Water on Mars is key for human survival on the Red Planet, not just for drinking but for growing food and making fuel and oxygen.
Despite all that we’ve learned about the Universe, there remain unanswered, and possibly unanswerable, questions. Could “God” be the answer?
13.8 billion years ago, the hot Big Bang gave rise to the Universe we know. Here’s why the reverse, a Big Crunch, isn’t how it will end.
If dark matter exists in a large halo in our galaxy, made up of particles, then it’s passing through us constantly. But how much?
Satellite imagery can help better predict volcanic eruptions by monitoring changes in surface temperature near volcanoes.
As technology advances, the use of laser weapons in space becomes more likely.
Phobos and Deimos only have two explanations, and neither one adds up.
If our Universe were born a little differently, there wouldn’t have been any planets, stars, galaxies, or chemically interesting reactions.
Boston Dynamics’ notorious robot goes on an interplanetary mission.
Even with leap years and long-term planning, our calendar won’t be good forever. Here’s why, and how to fix it.
The last image puts it all in perspective. Compared to what we find in our Solar System, galaxies are truly enormous. The Sun may be 109 times the diameter of […]
We give it the flight plan, and it takes care of the rest. It has to. Here’s why. No matter how advanced our technology becomes, there are certain limits that can […]
A new study proposes that Hawking radiation could be used to find dark matter in places like primordial black holes.
Many contrarians dispute that cosmic inflation occurred. The evidence says otherwise.
Theoretically, we know what happened on the red planet. Here’s how we’ll find out whether we’re right. When it comes to the worlds beyond Earth in our Solar System, it’s only […]
Where did the “seed” magnetic field come from in the first place?
It had long seemed impossible that supermassive black holes could grow to such enormous sizes. But the biggest problem is now solved.
No matter how your year went, Hubble’s views of the Universe never disappoint. Year after year, Hubble’s telescopic views are unparalleled. Saturn, its rings, and 5 of its moons are […]
The Kardashev scale ranks civilizations from Type 1 to Type 3 based on energy harvesting.
Already 14 billion miles from the Sun, Voyager 1 is speeding away at 38,000 mph.
