Look how tiny JWST's view of the sky is, especially compared to Euclid's wide field of view.
#JWST took an image of the very top of the Horsehead Nebula, focusing in on a region that transitions from a dense, warm area of gas and dust (blue) to an area of hot, ionized gas (red).

Wooooaaahhhh!
The new JWST image of a small bit of the Horsehead Nebula is INCREDIBLE.
To give you a sense of scale here, here’s an image of the nebula from my backyard. That small white box … that’s the JWST field of view! 🤯🤯🤯
Look at ALL those galaxies, all in that tiny white box.

Our galaxy seems to be full of "rogue" planets wandering alone between the stars.
A new observation from NASA's TESS space telescope hints that these dark worlds might hugely outnumber the normal (?) planets, like Earth, that bask in the warmth and light of a sun.

The formation of transiting circumplanetary debris discs from the disruption of satellite systems during planet-planet scattering
Several stars show deep transits consistent with discs of roughly 1 Solar radius seen at moderate inclinations, likely surrounding planets on eccentric orbits.arXiv.org
#OTD in 1910.
Halley's comet reappears after 76 years, and Mark Twain dies at his home, Stormfield, the day after the comet's perihelion. In his autobiography, Twain wrote, "I came in with Halley's comet in 1835. It's coming again next year (1910), and I expect to go out with it. The Almighty has said no doubt, 'Now here are these two unaccountable freaks; they came in together, they must go out together.'"
Heads Up!
Extremely Rare #citizenScience opportunity for #astronomy #astrophysics #astrodon #universeodon enthusiasts!
This year, there will be a nova, before or by September, as bright as the North Star.
After peak brightness it will remain bright enough, for several days, to observe with binoculars.
You can help research scientists with observational details.

1/ Most massive stellar #BlackHole in our galaxy found! With 33 times the mass of the Sun, this is the most massive black hole formed after the collapse of a star that we've found so far in the #MilkyWay.
ESA's Gaia mission found it via the wobble it induces on a star orbiting it, and data from ground-based telescopes helped confirm its mass and elucidate how it formed.

American astronomer Annie Jump Cannon died #OTD in 1941.
Cannon developed a system of stellar classification based on spectral characteristics, which became known as the Harvard Classification Scheme (she was one of the "Harvard Computers"). She classified hundreds of thousands of stars, organizing them by temperature and spectral characteristics. Her work laid the foundation for our understanding of stellar evolution and the composition of stars.

The astronauts aboard the ISS were amazed by the April 8 solar eclipse, just like the rest of us, and went crazy snapping photos from orbit.
They got some amazing views of the Moon's shadow sweeping across southern Canada & Maine, seen from 420 km (261 miles) above: https://www.flickr.com/photos/nasa2explore/with/53645140833 #space #eclipse #space #astronomy

Today's dose of cosmic beauty: Comet Pons-Brooks, photographed from southern Spain by Fritz Helmut Hemmerich.
The eerie green glow is from diatomic carbon. The ripples show the flow of the solar wind.

Eclipse news from 3,246 years ago:
The earliest well-established observation a solar eclipse was recorded on March 5, 1222 BCE. It was inscribed in a clay tablet from Ugarit, a city in modern-day Syria.

Amazing research out today:
The DESI survey has created the largest-ever 3D map of the structure of the universe.
It has also found intriguing (though tentative) evidence that cosmic "dark energy" is not what we thought -- a hint of new, unknown physics.
https://newscenter.lbl.gov/2024/04/04/desi-first-results-make-most-precise-measurement-of-expanding-universe/ #science #astronomy #space #tech
Seriously, how cool is this?
Cosmologists have now measured how the expansion of the universe changes over time, to an accuracy of 1%.
They did it by finding frozen sound waves from the Big Bang, and then tracking them across 11 billion years. People can do these things!

If you have the chance to see the upcoming solar #SolarEclipse on April 8, go for it! Even if you've seen an annular #eclipse or an almost total one, the difference between that and a fully total one is like night and day –– pun intended!
Here's a shot I snapped of the 2019 eclipse from ESO's La Silla Observatory in #Chile. I vividly remember seeing the #Moon 's shadow crawling towards us from the Pacific Ocean. Unforgettable!
