Most planets found by astronomers are “old” — they’re fully formed after millions of years pulling together elements around their star.
But researchers just located a baby giant exoplanet orbiting a young star just 330 light-years from Earth, making it the closest of its kind to us.
The planet is known as 2MASS 1155-7919 b, and it’s located in Epsilon Chamaeleontis Association, a young group of stars seen in our southern sky near the Chameleon constellation.

Iran Again Fails to Put Satellite Into Orbit - The New York Times
TEHRAN, Iran (AP) — Iran tried but failed to put a satellite into orbit on Sunday, state television reported, the latest setback for work that the United States says helps Tehran advance its ballistic missile program.
The launch of a Simorgh rocket in Semnan Province, about 145 miles southeast of Tehran, sought to put a communications satellite into orbit. It failed because of low speed, Iranian state TV reported.
Still, a Defense Ministry spokesman, Ahmad Hosseini, portrayed the failure as a "remarkable" achievement for Iran's space program. Previous launches of the Simorgh — or Phoenix — rocket also failed to put a satellite into orbit.
2 Russian satellites are stalking a US spysat in orbit. The Space Force is watching.
A U.S. spy satellite is being trailed by two Russian satellites, according to the commander of the U.S. Space Force .
Yesterday (Feb. 10), Gen. John "Jay" Raymond, the Space Force chief of space operations, revealed to Time magazine that a pair of Russian satellites have come extremely close, within 100 miles (160 kilometers) of the U.S. spy satellite.
"We view this behavior as unusual and disturbing," Raymond told Time magazine . "It has the potential to create a dangerous situation in space."
Will Elon Musk Create an Orbiting Garbage Pile Around Earth?
Each chunk of space debris, traveling 7,500 miles per hour around Earth, is like a bullet that can damage or destroy functioning satellites, spacecraft, and even the International Space Station.
But as bad as the problem is now, it's about to get a whole lot worse. Taking advantage of new, small electronics, more and more companies are developing "mega-constellations" of tiny, inexpensive satellites.

As those craft age out or break down, each mega-constellation could create thousands of orbital hazards on top of the thousands that already exist. "They pose a unique risk in that there are more objects," a spokesperson for the Federal Aviation Administration told The Daily Beast.

The Strait of Gibraltar As Seen From Orbit - SpaceRef
The Strait of Gibraltar connects the Atlantic Ocean with the Mediterranean Sea and separates Spain on the European continent from Morocco on the African continent.
The International Space Station was orbiting 265 miles above the Atlantic off the coast of Lisbon, Portugal, when this photograph was taken.

Amazon patents system for whipping payloads into the air, or into orbit – GeekWire
Although the application delves into the possibilities for boosting payloads to low Earth orbit, and then using orbiting platforms with tethers to transfer those payloads into even higher orbits, the inventors make clear there could be more mundane applications as well.
For example, smaller whips could send drones or other types of aerial vehicles into the air from ships at sea, or from planes in the air. Packages could be flung up on drones for processing on aerial fulfillment centers (an airship concept that's the subject of an earlier Amazon patent ).
NASA Space Station On-Orbit Status 12 February 2020 - Science Demonstration for Students -
Radio waves generate energy that can be harnessed for a variety of applications including wirelessly powering devices or possibly beaming solar energy down to Earth. NASA Flight Engineer Jessica Meir filmed how a flashlight powered by Wi-Fi gets brighter and darker as it moves closer or farther away from a Wi-Fi device aboard the station. The video will be sent down to students to demonstrate the technology developed by the Naval Research Laboratory.
Commander Oleg Skripochka of Roscosmos serviced Russian Orlan spacesuit water loops and checked for leaks. After checking on water tanks in the Progress 74 cargo craft, he set up exercise research gear then photographed the after effects of catastrophes on Earth.
We don't really know what we don't know in orbit

On the night of Jan. 29, two dead satellites headed toward each other 560 miles above Pittsburgh. Space is vast, but orbit isn't, and estimates placed the satellites at no more than 60 feet apart, roughly the length of two full-size school buses, as they passed. In the event of a collision, the blast would leave behind a cloud of debris, a hazardous gauntlet for other geocentric travelers that would threaten for years until gravity cleared the mess.
As details about the size, shape and paths of the satellites emerged, estimates of a collision ranged from 1 in 1,000 to 1 in 20.
