So Far, We Think The Sky Will Cooperate Enough For Us To See Tomorrow's Eclipse! We'll Be Handing Out

Make your Halloween pumpkin shine bright like a star observed by the James Webb Space Telescope! 🎃

The 8-point diffraction spikes are a signature look in Webb’s images of bright objects in the universe. Download the stencil or any of the other Webb patterns: https://webbtelescope.pub/46HNvPV

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

Wed. Oct. 22: We'll be open tonight from 7 - 8 pm. We expect some clouds, but we should still be able to catch some nice glimpses of the sky. Saturn is still the star of the show!

Happy Monday!

Today's picture of the day was taken by Matthew Dominick from the ISS! The image shows a giant jet lightning, which is a new discovery (only 23 years!) and associated with thunderstorms. While regular lightning travels between the ground and the clouds, giant jet lightning bursts upwards.

The Eagle nebula is a stellar nursery where new stars are born. 

Every February 2, we wonder if Punxsutawney Phil will see his shadow.

In Saturn’s case, astronomers know some of Saturn’s moons will cast shadows across the planet’s iconic rings every 15 years. This effect only occurs when the planet’s rings are perpendicular to the Sun. The next time this will happen is in May 2025.

Watch as four of Saturn’s moons orbit the planet, based on images taken by the Hubble Space Telescope over a 9.5-hour span in 1995. Enceladus is first and Mimas is close behind. Both of these moons cast small shadows on Saturn, but among the two, only Enceladus’ shadow cuts across the rings. Dione follows next and casts a long shadow across the planet’s rings. About 12 seconds in, the moon Tethys moves swiftly behind the planet toward the right.

The NGC 70 Group // Michael Legary

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.

Webb + Hubble > peanut butter + chocolate? We think so!

In this image of galaxy cluster MACS0416, the Hubble and James Webb space telescopes have united to create one of the most colorful views of the universe ever taken. Their combination of visible and infrared light yields vivid colors that give clues to the distances of galaxies (blue = close, red = far).

Looking at the combined data, scientists have spotted a sprinkling of sources that vary over time, including highly magnified supernovas and even individual stars billions of light-years away.

ALT TEXT: A field of galaxies on the black background of space. In the middle, stretching from left to right, is a collection of dozens of yellowish spiral and elliptical galaxies that form a foreground galaxy cluster. They form a rough, flat line along the center. Among them are distorted linear features, which mostly appear to follow invisible concentric circles curving around the center of the image. The linear features are created when the light of a background galaxy is bent and magnified through gravitational lensing. At center left, a particularly prominent example stretches vertically about three times the length of a nearby galaxy. A variety of brightly colored, red and blue galaxies of various shapes are scattered across the image, making it feel densely populated. Near the center are two tiny galaxies compared to the galaxy cluster: a very red edge-on spiral and a very blue face-on spiral, which provide a striking color contrast.

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.
