Problem with our neighborhood fusion generator

PhilStooke, 1 month ago to random

We got our first good look at non-spherical objects with Mariner 9 at Mars, when it imaged Phobos and Deimos.

Phobos has about a 50% difference between its longest and shortest radii. How can we map that with standard map projections? Or do we need new ones?

Collapse of the main span of the Francis Scott Key Bridge in Baltimore after a Singapore-flagged container ship Dali collided with one of its support pillars around 01:27 a.m. EDT.

Number of vehicles and people fell into the water 185 feet below.

The bridge is part of the outer beltway around Baltimore and sits above the shipping lanes of one of the busiest ports on the east coast.

The main NS highway I-95 is not affected.

Watch this satellite obliterate the Kuiper Belt object moving through this set of images.

The dumb satellite is so bright that our auto-detect software threw out the whole stack, because it destroyed the average brightness.

It pisses me off to no end that my taxpayer-funded telescope time is now less and less effective because of one for-profit private company.

(P.S. software dudes: please don't try to mansplain workarounds, believe me, a LOT of astronomers are working hard on this)

A gif of a Kuiper Belt object slowly moving across a set of images. It just looks like a fuzzy dot. Toward the end of the sequence, there's a super bright diagonal line that covers up the moving dot - that was a satellite.

Big step forward for space science today, with two new missions adopted into the #ESA science programme:

1. EnVision – probing Venus with imagers, spectrometers, & a synthetic aperture radar to characterise the atmosphere & surface of our nearest neighbour in unprecedented detail.

2. LISA – a space gravitational wave observatory to understand the physics of some of the most powerful events in the Universe, including the mergers of supermassive black holes.

Researchers have developed the first 3D maps of magnetic field structures within a spiral arm of the Milky Way. While we've seen smaller-scale magnetic fields before, this is much larger, showing the overall magnetic pattern in our galaxy. These fields are incredibly weak, about 100,000 times weaker than the Earth's magnetic field, but they impact the galaxy, strongly influencing star-forming regions.

The venerable Voyager 1 spacecraft is experiencing another glitch. Instead of sending science and engg. data, it is sending a 0101 bit pattern.

The problem has been narrowed down to the flight data system (FDS), which is not communicating properly with the telecom unit (TMU). A reboot did not help.

Stay tuned as NASA engrs work out a fix for this 1970's era computer, which has performed magnificently during its long 46-year journey to the planets and to outer space.

After successfully returning samples of asteroid Bennu to Earth, NASA's OSIRIS-REx mission has moved on to the next phase of its journey, visiting near-Earth asteroid Apophis. With a new destination, it got a new name: OSIRIS-APEX. But the journey will be difficult because it has to make a series of close passes to the Sun, risking its electronics to the heat and radiation from our star. It will position one of its solar panels as a shade to protect its electronics.

Harvard astronomer's "alien spherules" are industrial pollutants (bigthink.com)

Finding alien technology on the seafloor would be truly incredible. This extraordinary claim, however, is debunked by the actual evidence.

Did some super quick banding denoise (left lots of artifacts) on the HH211 data. But look, there's a whole other field over there! I find myself once again wondering how nice this would look without that big gap in the middle.

Thanks to new techniques, astronomers are mapping the Universe with more precision, finding galaxies with more and less dark matter. Now astronomers think they've found one that's almost all dark matter with few stars. Dubbed "Nube", the galaxy contains about the same mass as the Large Magellanic Cloud, measuring 22,000 light-years across, with almost no stars inside it. This is the most massive and extended "Almost Dark Galaxy" astronomers have ever found.

There will be an annular solar eclipse visible on Saturday, October 14 from many parts of North America.

A 🧵on how eclipses work, and how you can predict them by just paying attention to cycles, no computers or 3D models of the solar system necessary.

Looks like the Psyche mission will launch today - at 10:19 a.m. EDT.

Weather situation is not as bad as forecast yesterday. 85% favorable today.

Here is a graphic illustrating the sequence of events from launch to Psyche deployment about an hour later.

See the Psyche press kit at https://d2pn8kiwq2w21t.cloudfront.net/documents/psyche-press-kit.pdf for lots of details about the mission to the metal-rich asteroid Psyche.

How the surprising muon revolutionized particle physics

In the 1930s, known subatomic particles were the proton, neutron, electron, and photon.

Then the surprising muon came along, and nothing was ever the same again.

The sample was collected from the asteroid Bennu in October 2020 by NASA’s OSIRIS-REx spacecraft. On Wednesday, Oct. 11, NASA will unveil the sample and host a media teleconference with experts from the agency and the University of Arizona. Credit: NASA/Keegan Barber

The full landing sequence of #Chandrayaan3

I wrote a python script to undo the frame blending from the original video and then upscaled the images with AI.
The video is at 120x playback speed, in reality this took about 66 minutes.

Video of Chandrayaan 3 landing on the Moon. The side of the lander with it's solar panels is visible on the left side of the video. On the right side, the lunar surface moves by, it starts at an altitude of 30km with the lunar limb visible. As the craft descends a few larger craters become visible. Shortly before touchdown it stops briefly above the ground to assess the terrain, then proceeds to land.
