Now in orbit! :rock:

The first hurdle is vaulted.

Glad to see it made it into space without incident!

Astronomers See Black Hole Jets Blaze 16x Wider Than The Full Moon in Our Sky

Astronomers have captured a breathtaking radio wave image, showing our closest radio active black hole spewing out massive jets of plasma that span more than 16 times the size of the full moon in our sky.

The supermassive black hole in question is located in the center of the galaxy Centaurus A around 12 million light-years away.

The black hole has a jaw-dropping mass of around 55 million Suns but isn't visible in the image. It would be located within the small empty patch in the center of the two butterfly wing-like lobes.

When viewed from Earth, like it is in this photo, the plasma erupting from Centaurus A's black hole extends eight degrees across the sky, or the length of 16 full moons laid next to each other.

If that's not crazy enough, consider this for a second – those dots in the background of the image aren't stars. They're radio galaxies like Centaurus A, just located much further away.

And the galaxy itself isn't fully visible in this image because the radio jets are over a million light-years long, stretching well beyond Centaurus A.

Where is Webb?

An explainer on why the JWST is being put in the L2 postion, and WFT is the L2 position.

I'm kind of sad that the mission can only last 10 years, but I see the need for it to be at L2.

There's been a lot of hubbub surrounding Don't Look Up, a recent Netflix movie about a planet-killing comet heading towards Earth, but 2022 is actually a great year to turn your eyes to the sky.

There will be missions to Mars and the moon, a dance of planets and eclipses to enjoy. And better yet, no giant comet that threatens to destroy life as we know it on Earth.

Here are just some of 2022's space-related events to keep an eye on. ... -1.6300681

Peak viewing of the Quadrantid meteor shower tonight, at least in this part of the world. Freaking cold though, but that's the price you pay for clear skies in the winter.

Upper stage from failed Russian rocket to make uncontrolled re-entry

This Persei stage, tracked as IPM 3/Persey, is now well below 200 km and will likely make an uncontrolled re-entry into Earth's atmosphere on Wednesday. Hopefully, it will do so over an ocean.

2029 will be the perfect year to launch a mission to Sedna


Object 90377 Sedna—a distant trans-Neptunian object known best for its highly elliptical, 11,390-year long orbit—is currently on its way toward perihelion (its closest approach to the sun) in 2076. After that, Sedna will swing out into deep space again and won't be back for millennia, making this flyby a once-in-a-lifetime (or, once in ~113 lifetimes) opportunity to study an object from the far reaches of our solar system. There are no missions to Sedna in the works just yet, but astronomers are beginning to plan for the possibility, and the ideal launch date for such a mission is approaching fast, with two of the best launch windows coming up in 2029 and 2034.

Sedna was discovered in 2003 by Caltech astronomer Mike Brown and his team, and was one of a series of potential dwarf planets (alongside similar-sized bodies like Haumea, Makemake, and Eris) whose discovery led to the demotion of Pluto in 2006. As best we can tell from a distance, Sedna is about the same size as Ceres, the largest object in the asteroid belt, but its composition and origins are different. Its chemical makeup suggests it may be covered in deep reddish organic compounds known as tholins, the same material seen on Pluto and other Kuiper belt objects. Unlike Pluto, it is usually too cold for the methane abundant on its surface to evaporate and fall back as snow, though Sedna may briefly gain an atmosphere of nitrogen as it approaches the sun.
