Witness The Very Last Scream of Light From a Star Devoured by a Black Hole
From the heart of a galaxy 215 million light-years away, a brilliant flash of light flared into the void of space - the last scream of light from a dying star as it veered too close and was pulled apart by a supermassive black hole.

This spacecraft is being readied for a one-way mission to deflect an asteroid
Can slamming into a space rock at 15,000 miles per hour prevent it from hitting Earth? The DART mission aims to find out.

Cross your fingers. The delays will be OK as long as they get it right. There is absolutely no room for error.
What amazes me is the Hubble Space Telescope orbits less than 350 miles from Earth, while the Webb Space Telescope is supposed to orbit anywhere between 230,000 and 930,000 miles from Earth. Big difference. When the Hubble telescope had a problem (the primary mirror was slightly polished wrong), NASA sent Space Shuttles to Low Earth orbit and had the astronauts space walk and fix it. NASA can't do that a half a million miles away from Earth (not to mention, no more Space Shuttles).
If successful, we'll learn a lot more about our amazing universe.

It's an infra red jobby. Isuspect it needs to get away from the Earth's heat signature. The aliens will keep it maintained.
In JUST 4 years? Still pretty awesome to think just how close we are to this.

Nobel Prize in Physics Winner: "It's Unbelievable All That's Going On at the Moment in Astronomy"
German astrophysicist Reinhard Genzel was just awarded the Nobel Prize in physics. In an interview, he talks about how he discovered the black hole at the center of the Milky Way.

Interesting interview. Interesting universe. Still far more questions than answers. We probably know only about 1/googol (1/googolth?) of the answers. We truly are living in exciting times.
The Tunguska event has always fascinated me. Now new evidence indicates that we were VERY lucky and just avoided a civilization ending asteroid impact:
Tunguska explosion in 1908 caused by asteroid grazing Earth
A new theory explains the mysterious explosion in Siberia, scientists say, suggesting Earth barely escaped a far greater catastrophe.

Great pictures. It's pretty cool that we're landing on Asteroids and taking samples:

Still pretty amazing that we're landing on asteroids and bringing samples back to earth.
Asteroid samples tucked into capsule for return to Earth
A NASA spacecraft tucked more than 2 pounds of asteroid samples into a capsule for return to Earth after losing some of its precious loot because of a jammed lid, scientists said Thursday.

New hypothesis argues the universe simulates itself into existence
This article has been retracted.

- A new hypothesis says the universe self-simulates itself in a "strange loop".
- A paper from the Quantum Gravity Research institute proposes there is an underlying panconsciousness.
- The work looks to unify insight from quantum mechanics with a non-materialistic perspective.

Would they be mining it in order to travel further out? Seems a long hall to bring it back here.
As for that rock, they can talk about the value but if it were anywhere near here and possible to bring the minings down here, I think the market would collapse.

It's iron and nickel mostly. Could be used for a wide range of things. Who knows, Mars may end up being the Pittsburgh of the solar system

Interstellar space is far from empty:
phys.org
This realm, marked only by an invisible magnetic boundary, is where Sun-dominated space ends: the closest reaches of interstellar space.
In this stellar no-man's land, particles and light shed by our galaxy's 100 billion stars jostle with ancient remnants of the big bang. This mixture, the stuff between the stars, is known as the interstellar medium. Its contents record our solar system's distant past and may foretell hints of its future.
Measurements from NASA's New Horizons spacecraft are revising our estimates of one key property of the interstellar medium: how thick it is. Findings published today in the Astrophysical Journal share new observations that the local interstellar medium contains approximately 40% more hydrogen atoms than some prior studies suggested. The results unify a number of otherwise disparate measurements and shed new light on our neighborhood in space.
New evidence our neighborhood in space is stuffed with hydrogen

Scientists have dozens of theories about the causes of fast radio bursts, from colliding black holes to alien starships. Many theories suggest the bursts originate from neutron stars, which are corpses of stars that died in catastrophic explosions known as supernovas.
