New observations from the Very Large Telescope in Chile may have caught a Jupiter-like planet at its moment of birth around another star.

The universe just keeps on building more cool things.

Nature presents us with 80 "octaves" of light, of which humans can see exactly 1.

Bringing the other 79 octaves into view has taken two centuries of effort, but it has transformed our ability to sense our place in the cosmic order.

My new essay in Aeon magazine:

By tuning in to different microwave frequencies, ALMA can create snapshots of different components of the disks that surround newborn stars.

For the first time, we can see the swirls and waves that turn clouds of gas and dust into worlds like our own.

I recently visited the ALMA observatory in Chile. While I was poking around the telescopes, ALMA researchers released amazing new views of planet-forming disks around young stars.

These are the most detailed images yet of new solar systems being born.

Possibly the weirdest planet yet discovered?

Newfound world 2M1510 (AB) b appears to orbit not one but two stars...and they are actually failed stars, known as brown dwarfs...and the planet orbits sideways, in a unique up-and-down polar orbit.

Astronomers keep finding more to see in the iconic "Pillars of Creation."

An infrared view from JWST reveals stars being born in dusty cocoons. A matching image from Chandra exposes their violent side, as the baby stars create powerful flares & jets that blast out x-rays.

NOAA's new GOES-19 satellite continuously monitors solar activity, to protect satellites, communications & electrical systems. (It also regularly catches the Earth & Moon photobombing its view of the Sun.)

One small example of what NOAA funding does...

I look at a lot of space images, but this one made my eyes bug out like a cartoon character.

What you see here isn't a spiral galaxy, exactly. It's a spiral galaxy whose image was bent into a circle by the gravity of an elliptical galaxy visible at the center.

Warped space, right before your eyes!

Whoa: The European Space Agency's Solar Orbiter spacecraft got a spectacular view of Comet ATLAS (C/2024 G3) as it passed close to the Sun. Look at that enormous, splintered tail!

This comet won't be seen again for another 600,000 years.

Here it is: The first clear image of an eclipse of the Sun by the Earth, taken from the surface of the Moon.

This is what last night's lunar eclipse looked like from the Blue Ghost lander's perspective on the Moon. Amazing!

The "smallest known galaxy" sounds like an oxymoron (akin to the old joke, "jumbo shrimp").

But the discovery of Andromeda XXXV, just one-millionth the size of our Milky Way, offers serious clues about how coherent structures form & survive in a chaotic universe.

I loved working on this article:

The technology in your cell phone has a hidden connection to the stars. Modern computer chips are made using ultraviolet light from vaporized balls of tin--and those balls closely mirror the physics of supernova explosions!

Blue Ghost is on the Moon! Images are coming in now from what appears to be the first fully successful commercial lunar lander. Just look at that shadow.

Over the next 2 weeks, Firefly's Blue Ghost will drill, study lunar dust, and observe an eclipse of the Sun...by the Earth.

My friend Martin Ratcliffe recently shared his photo montage of the 2023 annular solar eclipse over Bryce Canyon, Utah.

I may be biased, but I think it's spectacular (and it got selected for an astronomy picture of the day).

Meanwhile, far from Earth...

The space between stars is full of gas and dust that is normally dark & invisible to us. But a flash of light from a 350-year-old supernova has lit up the interstellar medium -- revealing it in all its strange, swirling glory.

A neutron star merger produces a black hole, but also a significant amount of ejected matter. We know that a lot of stuff must be shot out because astronomers can see radiation from this material, which is observed as a kilonova.

See, eg: https://www.psu.edu/news/eberly-college-science/story/merging-neutron-stars-unfolding-story-kilonova-told-x-rays

You've probably heard that "we are stardust," but this graphic breaks it down further & tells you what kind of stars your dust came from--and which elements didn't come from stars at all.

This may be the strangest planet yet discovered. It seems to be a Pluto-size world circling the remains of three dead stars: two white dwarfs & a pulsar, as massive as the Sun but no bigger than Brooklyn.

If confirmed, it would also be the smallest exoplanet known.

A reminder that humans are capable of great acts of wonder when we work together & embrace knowledge.

An international team of astronomers has discovered swarms of cold comets circling 74 nearby stars -- and got clear pictures of these "exocomet belts."

A Canadian man narrowly avoided being struck by a meteorite that crashed into the walkway outside his home.
The offending space rock has since been bagged & tagged.
