NASA’s Transiting Exoplanet Survey Satellite (TESS) has been busy. Clocking in over 5000 exoplanet candidates, the researchers who manage the telescope’s data have enlisted an army of volunteer classifiers to sift through its data to confirm whether these planets exist. In a new paper in Astronomy & Astrophysics, some researchers from Brazil think they have found three planets that almost certainly do – and they happen to orbit stars that are very similar to our own Sun.

Astronomers Find 100,000-light-year Bow Shock in the Milky Way’s Outskirts
New simulations showed astronomers where to look for evidence of a dwarf galaxy's bow shock as it crashes through the Milky Way's halo.
How the runaway greenhouse gas effect can destroy a planet's habitability — including Earth's
Scientists watched as a simulated planet was driven from a habitable Earth-like heaven to an inhospitable Venus-like hell as the result of a runaway greenhouse effect, delivering a stark climate message.
A Radio Telescope on the Moon Could Help Us Understand the First 50 Million Years of the Universe
In the coming decade, multiple space agencies and commercial space providers are determined to return astronauts to the Moon and build the necessary infrastructure for long-duration stays there. This includes the Lunar Gateway and the Artemis Base Camp, a collaborative effort led by NASA with support from the ESA, CSA, and JAXA, and the Russo-Chinese International Lunar Research Station (ILRS). In addition, several agencies are exploring the possibility of building a radio observatory on the far side of the Moon, where it could operate entirely free of radio interference.
NASA laser-beams adorable cat video to Earth from 19 million miles away (video)
NASA's Deep Space Optical Communications experiment streamed a high-definition video of Taters the cat to Earth from 19 miles (31 million km) away in a groundbreaking demonstration.
Blue Origin launches New Shepard rocket on return to flight mission
A Blue Origin New Shepard rocket lifts off from the launch site in Van Horn, Texas, on the NS-24 mission. This was the first launch of a New Shepard rocket since the vehicle was grounded in the after math of the NS-23 anomaly. Image: Blue Origin
Updated 3:11 p.m. EST: Added comments and additional mission information from Blue Origin.
Why String Theory Requires Extra Dimensions
String theory found its origins in an attempt to understand the nascent experiments revealing the strong nuclear force. Eventually another theory, one based on particles called quarks and force carriers called gluons, would supplant it, but in the deep mathematical bones of the young string theory physicists would find curious structures, half-glimpsed ghosts, that would point to something more. Something deeper.
Pew! Pew! Pew! NASA's 1st successful two-way laser experiment is a giant leap for moon and Mars communications
NASA has completed its first laser link with an in-orbit laser relay system, marking a significant advancement in space communication technology.
Hubble Telescope captures a galaxy's 'forbidden' light in stunning new image
The "forbidden" light of the spiral galaxy MCG-01-24-014 is captured in a new image from the Hubble Space Telescope, suggesting the galaxy contradicts common rules of quantum physics.
Everything we know about 'Alien: Romulus'
Xenomorphs are invading the big screen once again with a movie from 'Evil Dead' helmer Fede Álvarez. Here's what we know about 'Alien: Romulus' so far.
James Webb Space Telescope may have found the oldest black hole in the universe
The James Webb Space Telescope's discovery of the universe's oldest black holes is giving astronomers some vital clues for how they came to be.
This alien planetary system has a Jupiter world 99 times wider than Earth
Astronomers found two planetary systems centered around solar analogs containing mini-Neptune planets and a "super-Jupiter" world 99 times the size of Earth.
Watch Artemis 2 moon crew take a slide for NASA training (video)
The next moon astronauts practiced sliding out of their Orion spacecraft during a simulated emergency splashdown. Artemis 2 aims to fly the four astronauts in 2024.
See the last half moon of 2023 swim with the fish of Pisces tonight
The moon reaches its first quarter moon phase on Dec. 19, crossing the sky in the Pisces constellation as the last half-moon of 2023.
Bolivia’s hypergravity blood cell test for astronaut health
The latest international group to employ ESA’s hypergravity-generating Large Diameter Centrifuge is an all-female team from Bolivia, with access sponsored by the United Nations and ESA. The researchers are investigating whether the high gravity levels experienced during rocket launches might contribute to the anemia afflicting many astronauts in space.
Gaia's 10th anniversary

SpaceX launched a Falcon 9 rocket from Cape Canaveral Monday night after high winds kept the rocket grounded last week. Liftoff of the Falcon 9 with 23 Starlink satellites occurred at 11:01 p.m. EST (0401 UTC).
Millions of Satellites Could Have a Profound Effect on the Earth’s Ionosphere
Hardly a day goes by where a story hits the headlines about our abuse of the Earth’s precious environment be that the atmosphere or the oceans, forests or desert. When it comes to the atmosphere we all tend to immediately turn our attention to pollution, to gasses being released and disturbing the delicate balance. Yet a paper recently published points to a new demon, megaconstellations of satellites damaging the ionosphere – the ionised part of the upper atmosphere.
The Holographic Secret of Black Holes
As weird as it might sound, black holes appear to be holograms.
Space weather will drag NASA's NEOWISE asteroid-hunting probe back to Earth in 2025
After more than a decade of hunting for asteroids and comets, the days of NASA's NEOWISE mission are officially numbered, thanks to our increasingly active sun.
