Hidden Orion from Webb Image Credit & License: NASA, ESA, CSA, JWST; Processing: M. McCaughrean & S. Pearson

Explanation: The Great Nebula in Orion has hidden stars. To the unaided eye in visible light, it appears as a small fuzzy patch in the constellation of Orion. But this image was taken by the Webb Space Telescope in a representative-color composite of red and very near infrared light. It confirms with impressive detail that the Orion Nebula is a busy neighborhood of young stars, hot gas, and dark dust. The rollover image shows the same image in representative colors further into the near infrared. The power behind much of the Orion Nebula (M42) is the Trapezium - a cluster of bright stars near the nebula’s center. The diffuse and filamentary glow surrounding the bright stars is mostly heated interstellar dust. Detailed inspection of these images shows an unexpectedly large number of Jupiter-Mass Binary Objects (JuMBOs), pairs of Jupiter-mass objects which might give a clue to how stars are forming. The whole Orion Nebula cloud complex, which includes the Horsehead Nebula, will slowly disperse over the next few million years.

I see an angry fox about to breathe fire.

The brown dwarf W1935 is a bit of a mystery. Astronomers using the James Webb Space Telescope picked up glowing methane—a sign that the object’s upper atmosphere is being heated. But the brown dwarf has no host star, so where could the heat be coming from?

In our solar system, Jupiter and Saturn show methane emission due to the presence of auroras—what we call the Northern Lights on Earth. W1935 might also have auroras, which could be powered by energetic particles from a nearby, active moon, like Jupiter’s Io: https://webbtelescope.pub/4aKMkBF

Top Study Tips from NASA

Study smarter this school year! We asked scientists, engineers, astronauts, and experts from across NASA about their favorite study tips – and they delivered. Here are a few of our favorites:

Study with friends

Find friends that are like-minded and work together to understand the material better. Trading ideas with a friend on how to tackle a problem can help you both strengthen your understanding.

Create a study environment

Find a quiet space or put on headphones so you can focus. You might not be able to get to the International Space Station yet, but a library, a study room, or a spot outside can be a good place to study. If it’s noisy around you, try using headphones to block out distractions.

Take breaks

Don’t burn yourself out! Take a break, go for a walk, get some water, and come back to it.

We'll be open tonight, Wed. 4/23, 8:30 - 9:45 pm! We expect lovely skies.

Wonderous strange! This unusual arrangement in the sky was one of only 100 known polar-ring galaxies when it was captured by the Hubble Space Telescope in 1999. Officially known to astronomers as NGC 4650A, the polar-rings may be the result of two galaxies colliding. Gas from the smaller galaxy would have been stripped off and captured by the larger galaxy, forming a new ring of dust, gas, and stars, which orbit the inner galaxy almost at right angles to the old disk. In addition to learning about galaxy interaction, astronomers use polar-ring galaxies like this to study dark matter, which does not emit light or interact with normal matter (except through gravity), making it difficult to understand. Both the old, rotating disk and the dark matter surrounding this galaxy pull on its polar ring. The alignment of the ring along the pole of the inner disk's rotation allows scientists to probe this combination of tugs and thus the distribution of dark matter. Credit: NASA, ESA, STScI. ALT TEXT: Two galaxies appear to intersect at right angles. Vertically there is a bright column of dust and stars, and horizontally there is a smaller hazy yellow band, brighter at its center, with no discernable stars. In the space around and behind the intersecting forms are smaller stars and distant galaxies colored yellow and red.

NASA’s Webb Snaps Supersonic Outflow of Young Star

This image of HH 211 from NASA’s James Webb Space Telescope reveals an outflow from a Class 0 protostar, an infantile analog of our Sun when

Take-aways:

This is a baby star imaged in stunning detail

Stars are born violently - there's hot gas striking the other gas and dust around it, making these amazing patterns

This particular baby star will one day be like the Sun 💖

Wed. Nov. 15 - Tonight's forecasts are inconsistent- we'll wait a few hours to decide if we'll open.
