UPDATE: New measurements show moon has hazardous radiation levels
Say WHAT?
:o
So, was there less radiation in 1969, or did all that jumping around and stuff help those dudes fight cancer...Future moon explorers will be bombarded with two to three times more radiation than astronauts aboard the International Space Station, a health hazard that will require thick-walled shelters for protection, scientists reported Friday.
If there was less radiation back then, what happened?
Is global warming to blame?
Inquiring minds want to know!

↑ Not really fresh news, the whole of space is full of radiation (fast protons and hard UV from the Sun + cosmic rays, which can be anything), so we fragile meatbags better stay under our cushy atmosphere. And send robots.

https://i.imgur.com/j8lFPLp.jpg
Does the Sun set in the same direction every day? No, the direction of sunset depends on the time of the year. Although the Sun always sets approximately toward the west, on an equinox like today the Sun sets directly toward the west. After today's September equinox, the Sun will set increasingly toward the southwest, reaching its maximum displacement at the December solstice. Before today's September equinox, the Sun had set toward the northwest, reaching its maximum displacement at the June solstice. The featured time-lapse image shows seven bands of the Sun setting one day each month from 2019 December through 2020 June. These image sequences were taken from Alberta, Canada -- well north of the Earth's equator -- and feature the city of Edmonton in the foreground. The middle band shows the Sun setting during the last equinox -- in March. From this location, the Sun will set along this same equinox band again today.

Well duhh... the moon landing hoaxtards say the Van Allen radiation belt would have fried anyone. This is true but (slaps ample butt) it wasn't like they lounged around there.

https://apod.nasa.gov/apod/astropix.htmlFilaments of the Cygnus Loop
https://i.imgur.com/b5qqK9A.jpg
What lies at the edge of an expanding supernova? Subtle and delicate in appearance, these ribbons of shocked interstellar gas are part of a blast wave at the expanding edge of a violent stellar explosion that would have been easily visible to humans during the late stone age, about 20,000 years ago. The featured image was recorded by the Hubble Space Telescope and is a closeup of the outer edge of a supernova remnant known as the Cygnus Loop or Veil Nebula. The filamentary shock front is moving toward the top of the frame at about 170 kilometers per second, while glowing in light emitted by atoms of excited hydrogen gas. The distances to stars thought to be interacting with the Cygnus Loop have recently been found by the Gaia mission to be about 2400 light years distant. The whole Cygnus Loop spans six full Moons across the sky, corresponding to about 130 light years, and parts can be seen with a small telescope toward the constellation of the Swan (Cygnus).

Re: Cool astronomy photos
This is one of the coolest discoveries I've ever seen...
https://apod.nasa.gov/apod/ap200929.html
It's a solar system with 3 stars. Besides being cool, it shouldn't even exist. There is a classic physics conundrum called the Three Body Problem.
https://en.m.wikipedia.org/wiki/Three-body_problem
Basically, the whole reason we only see single and binary solar systems is because three stars don't seem to form a stable orbit. One of the three quickly gets chucked. There are special and bizarre mathematical solutions to the 3 body problem, but this is the first real life example that I'm aware of.
The painfully brief paragraph about this system indicates that it could break apart in the near future, or that it may be in the process of breaking apart, but the fact that the system formed such beautiful concentric rings indicates that it has remained relatively stable for quite a long time. Would love to see more study on this system and would love to know if the orbits follow on of the mathematical 3 body solutions. 8)

Re: Cool astronomy photos
Not to be pedantic, but I don't think the three body problem means that trinary star systems don't exist. It just means that it's difficult to predict how they will behave using Newton's laws of motion. Not impossible, but difficult.

Re: Cool astronomy photos
He simply excludes that we are fortunate in that the bodies in our planetary system are largely in the same plane. A fact easily overlooked by any unimaginative street-fool. :)

HubbleESA
This video shows a unique time-lapse of the supernova in galaxy NGC 2525. The supernova is captured by Hubble in exquisite detail within this galaxy in the lower left portion of the frame. It appears as a very bright star located on the outer edge of one of its beautiful swirling spiral arms. This new and unique time-lapse of Hubble images shows the once bright supernova initially outshining the brightest stars in the galaxy, before fading into obscurity during the telescope’s observations. This time-lapse consists of observations taken over the course of one year, from February 2018 to February 2019.
NGC 2525 is located nearly 70 million light-years from Earth and is part of the constellation of Puppis in the southern hemisphere. Hubble captured this series of images of NGC2525 in 2018 as part of one of its major investigations; measuring the expansion rate of the Universe, which can help answer fundamental questions about our Universe’s very nature.
The whole galaxy for reference:

Most of the time they are out at sea, and won't come back to base if the situation gets tense. Not the same role as submarines during WWII.

Re: Cool astronomy photos
I see two. One is in the lower left quadrant moving from left to right. a second one is in the lower right quadrant at about the level and moving from 10 o'clock to 4 O'clock.
There also seems to be a movement near the second-largest star near the top and slightly to right of center in the image. Like something appears and disappears.

Re: Cool astronomy photos
This is exactly what I expected a proto-planet to look like at the point in between agglomeration and the point where gravity starts to crush the cluster of boulders into a spherical shape. Very cool.

Re: Cool astronomy photos
Not really news (2010), but interesting factoid:
https://science.nasa.gov/science-news/s ... oststripe/ for the rest.Big Mystery: Jupiter Loses a Stripe
Lost: A giant belt of brown clouds big enough to swallow Earth twenty times over. If found, please return to Jupiter.
May 20, 2010: In a development that has transformed the appearance of the solar system's largest planet, one of Jupiter's two main cloud belts has completely disappeared.
"This is a big event," says planetary scientist Glenn Orton of NASA's Jet Propulsion Lab. "We're monitoring the situation closely and do not yet fully understand what's going on."
https://i.imgur.com/dWOBAxH.jpgKnown as the South Equatorial Belt (SEB), the brown cloudy band is twice as wide as Earth and more than twenty times as long. The loss of such an enormous "stripe" can be seen with ease halfway across the solar system.These side by side images of Jupiter taken by Australian astrophotographer Anthony Wesley show the SEB in August 2009, but not in May 2010.
"In any size telescope, or even in large binoculars, Jupiter's signature appearance has always included two broad equatorial belts," says amateur astronomer Anthony Wesley of Australia. "I remember as a child seeing them through my small backyard refractor and it was unmistakable. Anyone who turns their telescope on Jupiter at the moment, however, will see a planet with only one belt--a very strange sight."
Wesley is a veteran observer of Jupiter, famous for his discovery of a comet hitting the planet in 2009. Like many other astronomers, he noticed the belt fading late last year, "but I certainly didn't expect to see it completely disappear," he says. "Jupiter continues to surprise."

https://www.independent.co.uk/life-styl ... 09506.htmlNasa to make major announcement of ‘exciting news’ about the moon
Nasa will hold a major event to announce an “exciting new discovery” about the Moon, it has said.
The space agency did not reveal details about the discovery, but said that it “contributes to Nasa’s efforts to learn about the Moon in support of deep space exploration”.
It also said that the discovery had come from the Stratospheric Observatory for Infrared Astronomy, or Sofia.
Sofia is a modified Boeing 747 that flies higher than much of the atmosphere, allowing its built-in, 9-foot telescope to get a clear view of our solar system and the broader universe. The plane is able to get up above 99 per cent of the atmosphere’s water vapour, which normally obscures our view of space.
The telescope instruments at the centre of the flying observatory gather infrared light, meaning it can “pick up phenomenon impossible to see with visible light”, Nasa noted in its announcement.
...
Nasa’s notice of the event made heavy reference to the Artemis programme, which hopes to send the first woman and next man to the Moon in 2024, with the hope of using it as a base to launch missions to Mars from the 2030s. They will be the first people to set foot on the Moon since 1972.
...
The event will take place at noon eastern time, or 5pm in the UK, on Monday, 26 October, Nasa said. Audio will be streamed live on its website.

https://apod.nasa.gov/apod/astropix.htmlReflections of the Ghost Nebula
Do any shapes seem to jump out at you from this interstellar field of stars and dust? The jeweled expanse, filled with faint, starlight-reflecting clouds, drifts through the night in the royal constellation of Cepheus. Far from your own neighborhood on planet Earth, these ghostly apparitions lurk along the plane of the Milky Way at the edge of the Cepheus Flare molecular cloud complex some 1,200 light-years away. Over two light-years across and brighter than the other spooky chimeras, VdB 141 or Sh2-136 is also known as the Ghost Nebula, seen at toward the bottom of the featured image. Within the reflection nebula are the telltale signs of dense cores collapsing in the early stages of star formation.
