Hubble Sees Beautiful Globular Cluster: NGC 1805 | Astronomy | Sci-News.com
The NASA/ESA Hubble Space Telescope has captured the brilliance of a globular cluster called NGC 1805.
Here's what we know.
The Chinese government has announced a first – they have successfully landed a reusable spacecraft safely back on Earth after it spent two days in orbit.
This fall will be a great time to observe the planet Mars! Here's a photo from last night (9/05/2020) when it was within a degree of the Moon! (Photo taken from Arlington, VA).
If you enlarge the picture, you should be able to see Mars directly above the Moon.
Hubble Hubble: Telescope Provides Stunning New Images of Two Planetary Nebulas
Astronomers used Hubble's full range of imaging to dissect wild 'fireworks' happening in two nearby young planetary nebulas.
New High-Res Images of The Sun Show How Creepy Sunspots Look in Closeup
One of the most powerful solar observatories in the world has just completed a major upgrade. And now, the GREGOR solar telescope in Spain has taken some of the most high-resolution images of our Sun ever obtained in Europe.
But not for astronauts
The Moon is both seductively close to Earth and cosmically far away: Decades after the end of the space race, it remains extraordinarily expensive and difficult to actually get there.
Orion Hosts a Bizarrely Wonky Protoplanetary System With 3 Stars
A cloud of dust and gas swirling around an infant star system 1,300 light-years away is like no planet-forming disc we've seen yet. It consists of three rings, wrapped around three stars - and all three rings have different orientations, with the inn

Explanation: How many moons do you see? Many people would say one, referring to the Earth's Moon, prominent on the lower left. But take a closer look at the object on the upper right. That seeming-star is actually the planet Jupiter, and your closer look might reveal that it is not alone — it is surrounded by some of its largest moons. From left to right these Galilean Moons are Io, Ganymede, Europa and Callisto. These moons orbit the Jovian world just like the planets of our Solar System orbit the Sun, in a line when seen from the side. The featured single shot was captured from Cancun, Mexico last week as Luna, in its orbit around the Earth, glided past the distant planet. Even better views of Jupiter are currently being captured by NASA's Juno spacecraft, now in a looping orbit around the Solar System's largest planet. Earth's Moon will continue to pass nearly in front of both Jupiter and Saturn once a month (moon-th) as the two giant planets approach their own great conjunction in December.

Most Massive Black Hole Collision Detected Confirms Elusive Middleweight Black Holes
From 7 billion light-years away, a pair of colliding black holes has delivered up, on a shiny gravitational wave platter, one of the most sought-after detections in black hole astronomy - the extremely elusive 'middleweight' black hole, which lies in
Incoming Object With Earth Impact Trajectory Turns Out to Be Old NASA Spacecraft
With all sorts of rocks flying around willy-nilly in the space around Earth, telescopes around the world are keeping a careful eye on the sky to make sure we're not in any danger.
"It is a fascinating thought that the Universe may be packed with intelligent life that is so different from ours that we failed to recognise its existence,"
When searching for signs of life in the Universe, we tend to look for very specific things, based on what we know: a planet like Earth, in orbit around a star, and at a distance that allows liquid surface water. But there could, conceivably, be other
A Galaxy Far, Far Away Looks Like a TIE Fighter, Astronomers Discover Unexpectedly
Space has never been a one-size-fits-all affair. Our Universe is littered with gas and dust forming the shapes of faces, jellyfish, butterflies, giant pillars that look like a hand, and so much more.
UPDATE: SpaceX delays this morning's Starlink fleet launch due to weather.
Weather permitting, SAOCOM-1B will fly from SpaceX’s other Florida launch pad, at Space Launch Complex-40 at Cape Canaveral Space Force Station. That liftoff is scheduled for 7:18 p.m. EDT (2318 GMT).
If the weather cooperates.
Why fixing the Hubble constant could change how we see the Universe.
For as long as there has been a Universe, space has been expanding. It winked into existence roughly 13.8 billion years ago, and has been puffing up ever since, like a giant cosmic balloon.

There's a Theory Beyond Relativity That Would Allow You to Fly Through a Wormhole
Wormholes are a popular feature in science fiction, the means through which spacecraft can achieve faster-than-light (FTL) travel and instantaneously move from one point in spacetime to another.
Here's a lovely video made by Jeff Ball, an accomplished astrophotographer. He shows some of the beautiful images he has made at Spruce Knob in West VA.

Hubble Views Edge of Stellar Blast
This Hubble Space Telescope image depicts a small section of the Cygnus supernova blast wave, the result of the "death" of a star 20 times more massive than our Sun 10,000 to 20,000 years ago. Light from this supernova takes around 2,400 years to reach Earth.
There's a Strange Glow in The Centre of Our Galaxy, And It's Not What We Thought It Was
The centre of the Milky Way is glowing. Yes, there's a big chonkin' black hole there, and it's a very energetic region, but there's an additional high-energy, gamma-ray glow, above and beyond the activity we know about, and it's something that's yet
How big does a meteor have to be to make it to the ground?
Where I live it is pretty common to see "shooting stars" -- streaks of light in the sky at night. How big is a shooting star? Do they land on earth or do they burn up? Do they land on the ground as meteorites?
Water, Water, Every Where — And Now Scientists Know Where It Came From
Some unusual meteorites suggest that Earth got its water at its start, rather than forming dry and being watered by comets later on.
Hubble maps giant halo around Andromeda Galaxy
In a landmark study, scientists using NASA's Hubble Space Telescope have mapped the immense envelope of gas, called a halo, surrounding the Andromeda galaxy, our nearest large galactic neighbor. Scientists were surprised to find that this tenuous, nearly invisible halo of diffuse plasma extends 1.3....
New Evidence Finally Confirms The Theory of How Stars Get Shredded by Black Holes
When a star ventures a little too close to a black hole, we know - broadly - what happens. The intense tidal forces tear the star apart in what is called a tidal disruption event, unleashing a final burst of light before the star's debris passes beyo
Scientists Measured The Global Magnetic Field of The Sun's Corona For The First Time
The Sun's corona, its outer atmosphere of searing hot plasma, is a source of constant fascination for scientists – and in a major leap forward in our understanding, researchers have mapped out a region of its global magnetic field for the first tim
A team of astronomers in the United Kingdom has used a machine learning algorithm to analyze a sample of candidate exoplanets identified by NASA’s Kepler Space Telescope and determine which ones are real and which ones are false positives.

A massive link in space.
A rare merger between clusters of galaxies has just revealed an even rarer sight. Astronomers have found a vast, low-frequency radio 'bridge' between the two, spanning a 6.5-million-light-year distance - evidence of a magnetic field connecting them i
Astonishingly old Antarctic space rock could explain mystery of life's weird asymmetry
Life is asymmetrical, and a time capsule of the earliest days of the solar system may explain why.
Ancient skywatchers built hundreds of monuments to track the motion of the sun, moon, and even stars and planets. While Stonehenge is probably the most famous of these ancient sites, the Americas have many of their own. Come explore a few of these sites and learn how Native Americans were able to build huge cities aligned to the cardinal points and monuments that celebrated the solstices and equinoxes.
Just when you didn't think Comet NEOWISE could get any cooler!
When Comet NEOWISE streaked by Earth in July, we were dazzled by a plethora of stunning photographs of the twin-tailed space rock.
Invisible in the dark.
Hidden among the seeming endlessness of space, there could be countless worlds that never see the light of day. These mysterious bodies, called rogue planets, are not like other planets, although there could be multitudes of them.
Don’t forget to join us here on our page at 7:30pm (EDT) tonight (8/25/20) for a talk on American Archaeoastronomy sites!
The Earth's core is younger than previously believed, according to new research
A billion years may not sound young, but researchers estimating the age of the Earth's core say it could be between 1 and 1.3 billion years old -- which is at the lower end of previous estimates.
