What is Dark Energy? Inside our accelerating, expanding Universe - NASA Science

Some 13.8 billion years ago, the universe began with a rapid expansion we call the big bang. After this initial expansion, which lasted a fr

An artist’s rendering shows us what happens when a star gets a little too close to a massive black hole!

In case of confusion, the observatory is not open this Wednesday.

As consolation, here's the 'Great Turkey Nebula' of 2020 from Astronomy Picture Of The Day. I wonder what APOD's cooking this year?

Explanation: Surprisingly reminiscent of The Great Nebula in Orion, The Great Turkey Nebula spans this creative field of view. Of course if it were the Orion Nebula it would be our closest large stellar nursery, found at the edge of a large molecular cloud a mere 1,500 light-years away. Also known as M42, the Orion Nebula is visible to the eye as the middle "star" in the sword of Orion the Hunter, a constellation now rising in planet Earth's evening skies. Stellar winds from clusters of newborn stars scattered throughout the Orion Nebula sculpt its ridges and cavities seen in familiar in telescopic images. Much larger than any bird you might be cooking, this Great Turkey Nebula was imagined to be similar in size to the Orion Nebula, about 13 light-years across. Stay safe and well.

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

How Gravity Warps Light - NASA Science

Gravity is obviously pretty important. It holds your feet down to Earth so you don’t fly away into space, and (equally important) it keeps y

Dust and the Western Veil Nebula Image Credit & Copyright: Jiang Wu

Explanation: It’s so big it is easy to miss. The entire Veil Nebula spans six times the diameter of the full moon, but is so dim you need binoculars to see it. The nebula was created about 15,000 years ago when a star in the constellation of the Swan (Cygnus) exploded. The spectacular explosion would have appeared brighter than even Venus for a week - but there is no known record of it. Pictured is the western edge of the still-expanding gas cloud. Notable gas filaments include the Witch’s Broom Nebula on the upper left near the bright foreground star 52 Cygni, and Fleming’s Triangular Wisp (formerly known as Pickering’s Triangle) running diagonally up the image middle. What is rarely imaged – but seen in the featured long exposure across many color bands – is the reflecting brown dust that runs vertically up the image left, dust likely created in the cool atmospheres of massive stars.

We're not yet sure about tonight's weather - it depends on whether these clouds move north or south. Check back in a few hours!
