Earth and the Moon Are Growing Apart - The Atlantic

The moon is drifting away from us.

Each year, our moon moves distinctly, inexorably farther from Earth—just a tiny bit, about an inch and a half, a nearly imperceptible change. There is no stopping this slow ebbing, no way to turn back the clock.

The moon used to be closer. When it first formed, about 4.5 billion years ago, molded out of rocky debris that had been floating around Earth, the moon orbited 10 times nearer to the planet than it does today.

Blue Origin 'gambled' with its Moon lander pricing, NASA says in legal documents - The Verge

Jeff Bezos' Blue Origin "gambled" with its Moon lander proposal last year by hoping NASA would be willing to negotiate its $5.9 billion price tag, agency attorneys argued in blunt legal filings obtained by The Verge.

NASA officials haven't talked much about Blue Origin's legal quarrels beyond occasional acknowledgements that the company's protesting — first at a watchdog agency and now in federal court — is holding up the agency's effort to land humans on the Moon by 2024.

BATON ROUGE, La. (AP) — Louisiana has recovered a missing lunar rock gifted to the state to commemorate the last manned U.S. mission to the moon after it turned up in the hands of a man who recycles wooden plaques.

The rock from the 1972 Apollo 17 landing was in the possession of the Louisiana State Museum on Tuesday, The Advocate of Baton Rouge  reported .

NASA preps Lucy mission to study Jupiter’s Trojan asteroid swarms

NASA is set to launch a spacecraft next month on the agency's first mission to a group of asteroids near Jupiter.

The Lucy space probe is scheduled to lift off on an Atlas V rocket from Cape Canaveral Space Force Station in Florida on Oct. 16.

NASA's Juno spacecraft has been circling Jupiter since 2016, but this will be the agency's first expedition to study two swarms of space rocks at the gas giant — one group that orbits the sun ahead of Jupiter and another that trails behind the planet.

Warehouse-sized asteroid sneaks up on Earth by hiding near the sun - CNET

A space rock possibly as wide as a football field flew between the moon and Earth last week, but the big asteroid -- catalogued as 2021 SG -- wasn't spotted until the day after it had already made its closest pass by our planet.

That meteor was estimated to be only about one quarter the diameter of 2021 SG, and yet that was large enough to create a shock wave that blew out thousands of windows in the city below, injuring hundreds.

It's not uncommon for scientists to bring interesting objects thousands of miles to Argonne National Laboratory for study. But it's fair to say that the latest of these to land at the laboratory came from much, much farther away.

A team of scientists with Argonne and the University of Chicago is among the few groups around the world chosen to study tiny fragments of an asteroid. These dust particles came from 162173 Ryugu, part of a group of near-Earth objects called the Apollo asteroids.

Ways of Protecting Our Precious Planet from Asteroid Impacts

Unfortunately, we don't. What we do have in place are the first steps to protecting ourselves from incoming asteroids and meteors and that is detection. Our mighty telescopes do a great job of detecting any celestial objects that may be coming our way.

Data from these telescopes is scanned and analyzed to see if there are any moving objects and further calculate their corresponding trajectories. If a potential threat is identified, even more powerful telescopes are then used to obtain a better view of the incoming object.

7 amazing facts about Asteroids | Research Matters

1. Asteroids are relics from the time the solar system was born
Billions of years ago, when the solar system was forming, space dust and debris fused to form rocks and rubble. As the rocks churned, they rammed into one another, merged and formed planets and moons.

2. There are millions of asteroids in the solar system
Once Jupiter formed, its massive gravity held the remaining millions of space rocks captive and prevented them from forming more planetary bodies between Mars and itself.

Planet found orbiting 3 stars at once, with giant dust rings - Big Think

But GW Orionis, a young, planet-forming system just 1,300 light-years away, has multiple protoplanetary rings orbiting a triple star system.

A new study shows there must be planets in between those rings, making these the first planets discovered orbiting all three stars in a trinary system.

Most of the planets astronomers have found orbit only one star – a few orbit two, but so far we've never spotted an exoplanet that orbits three stars simultaneously. Now, researchers have spotted hints of a young world with three host stars.

These hints come from a stellar system called GW Orionis, which consists of two stars orbiting one another at about the same distance that Earth sits from the sun, and a third circling those two about eight times further …

A bigger nursery for the solar system's first formed solids

Calcium-Aluminum-rich inclusions (CAIs) in meteorites are the oldest dated solids that formed within the solar system. They carry crucial information regarding the environmental conditions of the earliest stages of the protoplanetary disk before any of the planets formed.

"Our findings indicate that CAI formation during molecular cloud infall and disk build-up likely occurred at greater distances from the sun that we thought before, potentially up to planet-forming regions of the solar system," said LLNL postdoc Quinn Shollenberger, a co-author of the paper.

It has been 15 years since Pluto—previously known as the ninth planet of the solar system—was demoted (sadly!) to the status of a dwarf planet. Some of us are still not over it! The decision to demote Pluto, while astronomically sound, was difficult to digest for sentimental reasons.

However, Michael Brown, one of the scientists who pushed for Pluto to be stripped of its planetary status, had no trouble moving on. He seems to have already found a replacement for the dwarf planet: the infamous Planet 9!

There Might Be a Mars-Like Planet Hiding in the Outer Solar System - ExtremeTech

If the 21st century has taught us any astronomical lessons, it’s that counting planets is hard. In 2000, there were nine planets, and now there are eight, but that might not last.

All the planetary uncertainty lies in the outer reaches of the solar system, beyond the orbit of Neptune. This is where Clyde Tombaugh discovered Pluto, which we thought was a planet for decades but has since been demoted to a dwarf planet.

GW Ori is a star system 1,300 light years from Earth in the constellation of Orion. It is surrounded by a huge disk of dust and gas, a common feature of young star systems that are forming planets. But fascinatingly, it is a system with not one star, but three.

As if that were not intriguing enough, GW Ori's disk is split in two, almost like Saturn's rings if they had a massive gap in between. And to make it even more bizarre, the outer ring is tilted at about 38 degrees.
