The light from Earendel took 12.9 billion years to reach Hubble. The star is millions of times brighter than our Sun and 50 times as massive.
If you want to find life in the Universe, this is how you do it. When it comes to uncovering the ultimate truths about reality, we can only reap what we […]
The surface and atmosphere is colored by ferric oxides. Beneath a very thin layer, mere millimeters deep in places, it’s not red anymore.
Lockheed Martin’s Skunk Works engineering division has devised many jaw-dropping aircraft. Here are some of the best — and one ship.
Isaac Newton and Albert Einstein are locked in an eternal battle over the nature of gravity. Whose side are you on?
How did the troughs form?
The space agency describes the process of landing rovers on Mars as “seven minutes of terror.”
Even with all the recent impacts we’ve seen, it might be more “foe” than “friend” to us.
Chemical changes inside Mars’ core caused it to lose its magnetic field. This, in turn, caused it to lose its oceans. But how?
An optical telescope with a massive 20-foot (6-meter) mirror has an eye-popping price tag of $11 billion.
Neptune holds records in our Solar System, but the Universe gets even faster. Here on Earth, extreme weather events can cause dramatic wind speed spikes. When hurricanes are at their most […]
There are over 100 known elements in the periodic table. These 8 ways of making them account for every one.
The truth is out there, but it’s probably not in the latest whistleblower’s report.
“The surface is no longer a record of every impact the moon has ever had, because at some point, impacts were erasing previous impacts.”
Was there ever life on Mars? Is there life on Mars now? Did it originate there or here, on Earth? All possibilities are fascinating.
At 35 light-years away, it’s also the 2nd coolest, 2nd widest planet ever found. Despite discovering more than 4000 exoplanets, most remain obscure. Although more than 4,000 confirmed exoplanets are known, […]
Gravitation, all on its own, can reveal what’s present in the cosmos like nothing else.
Researchers have discovered 830-million-year-old microbes living inside a salt rock on Earth. Could the same occur on Mars?
Our Sun will continue to grow, becoming a red giant and then a planetary nebula. Here’s how large it will get.
A newly discovered “ultrahot Jupiter” has the shortest orbit of any known gas giant.
An artist’s impression of what the fully-deployed James Webb Space telescope will look like from the perspective of an observer on the ‘dark’ (non-Sun-facing) side of the observatory. (NORTHRUP GRUMMAN) […]
With a telescope at just the right distance from the Sun, we could use its gravity to enhance and magnify a potentially inhabited planet.
2023 will see an “arms race” in mixed reality hardware and software. This truly will revolutionize our society.
The far infrared reveals both the coldest and hottest gas in the Universe, and can teach us what no other wavelength range can.
We are likely to see the first humans walk on Mars this decade.
50% of stars are in Sun-like ‘singlet’ systems. The planetary nebulae we see just don’t line up. Around 7 billion years from now, our Sun’s life will end. As the Sun […]
65 million years ago, an asteroid strike caused the 5th great mass extinction. Could we save Earth, today, from a similar event?
The sacrifices of early astronauts paved the way for Apollo’s successes, and so much more. In all of history, only 24 humans have ever escaped Earth’s gravity. The very first launch […]
