.css-14iz86j-BoldText{font-weight:bold;} Two items of space junk expected to pass close to one another have avoided collision, said a company which uses radar to track objects in orbit.
LeoLabs had said a defunct Russian satellite and a discarded Chinese rocket segment were likely to come within 25m of each other.

Other experts thought Kosmos-2004 and the ChangZheng rocket stage would pass with a far greater separation.
Quite a lot has been going on:
Astronomers spot 2 planets orbiting a red dwarf star - SCIENCE News
Astronomers have found a "peculiar pair" of planets orbiting around a red dwarf star called TOI-1266. These planets are called exoplanets. According to a report in Science Daily , the Mexico-based SAINT-EX telescope, co-operated by the NCCR PlanetS, was used to spot the planets. SAINT-EX stands for Search And characterIsatioN of Transiting EXoplanets.
It "demonstrates its high precision and takes an important step in the quest of finding potentially habitable worlds," the report said.

In what is now a routine demonstration of rocket engineering the Falcon 9's first stage made a text-book landing onto its floating barge ('Of Course I Still Love You') and the Atlantic rescue/catching vessels (named Go Ms. Tree and Go Ms. Chief) managed to catch two valuable rocket fairings although one of the capture nets broke.
Scientists Discover Jupiter-sized Planet Orbiting a Tiny White Dwarf Star
A planet similar to the size of Jupiter has been found orbiting a tiny white dwarf star by an international team of astronomers. According to reports, the planet is about seven times larger than the white dwarf.
A statement issued by NASA revealed that the huge planet, known as WD 1856 b, was found using Nasa's Transiting Exoplanet Survey Satellite (TESS) and retired Spitzer Space Telescope. The satellite spotted WD 1856 b about 80 light-years away in the northern constellation Draco. It orbits a cool, quiet white dwarf that is roughly 11,000 miles (18,000 kilometres) across, maybe up to 10 billion years old. The planet appears to be a distant member of a triple star system.
This may worth something:
Scientists discover two exoplanets orbiting closely around a red dwarf star - Republic World
Scientists and astronomers have recently discovered a "peculiar pair" of planets orbiting around a red dwarf star called TOI-1266. As these planets are not a part of our solar system, they’ve been deemed as exoplanets. The Mexico-based SAINT-EX telescope, which is co-operated by the NCCR PlanetS, was used to spot the planets. Read on to know more about the intriguing new worlds.

Cosmonauts patch small air leak on International Space Station: reports | Space
Cosmonauts are making progress in the fight against the small air leak that has beleaguered the International Space Station for months, according to Russian reports.
* * *
Now, cosmonauts on the space station report that they tracked down the leak yesterday (Oct. 15) and attempted to patch it, according to reports from Russia's government-owned news service, Tass.
The cosmonauts also attempted to patch the leak, but their reports to mission control today (Oct. 16) suggest it might not hold, Tass reported: air loss has slowed, but the module is still losing air pressure, according to their measurements. The crew suggested reaching out to their American colleagues — currently Chris Cassidy and Kate Rubins — for a different type of patch mechanism.
The Monster At The Heart Of The Milky Way
Via UCLA Galactic Center Group : An animation of the stellar orbits. Images taken from the years 1995 through 2016 are used to track specific stars orbiting the proposed black hole at the center of the Galaxy. These orbits, and a simple application of Kepler’s Laws, provide the best evidence yet for a supermassive black hole, which has a mass of 4 million times the mass of the Sun.
The 2020 Nobel Prize winners have been announced, and among them is UCLA astronomer Andrea Ghez, who split the prize with Roger Penrose and Reinhard Genzel. Ghez, also the fourth woman to ever win the Physics prize, won for her 1998 work that resolved a decades-old debate among astronomers: What lurks at the difficult-to-observe heart of the Milky Way?
This Week in History: October 18-24 - RocketSTEM
OCTOBER 18, 1977: Charles K owal discovers the first-known c entaur, (2060) Ch iron, with the 1.2-meter Schmidt telescope at Palomar Observatory in California. Centaurs are the subject of a previous " Special Topics " presentation.
OCTOBER 18, 1989: NASA's Galileo mission is deployed from the Space Shuttle Atlantis, with its final destination being Jupiter. While en route to Jupiter Galileo made the first spacecraft flybys of asteroids, (951) Gaspra in 1991 and (243) Ida in 1993 – discovering the moon Dactyl orbiting around Ida in the process – and also observed some of the impacts of Comet Shoemaker-Levy 9 into Jupiter in July 1994.
