The James Webb Space Telescope has found a strange alien world shrouded in clouds of sand-like silicate grains.
The exoplanet discovery, described in a new paper as the first detection of its kind, was made by the James Webb Space Telescope's NIRSpec and MIRI instruments. In the data, astronomers spotted evidence of silicate-rich clouds around a brown dwarf nearly 20 times the size of Jupiter. The finding confirms some earlier theories about these odd planet-like worlds.
On Aug. 20, 1977, 45 years ago, an extraordinary spacecraft left this planet on a journey like no other. Voyager 2 was going to show us, for the first time, what the outer solar system planets looked like close-up. It was like sending a fly to New York City and asking it to report back.
Just the Facts, Ma'am "I stopped watching TV news a year ago, so sick of the bias everywhere. But in doing so, I was out of the loop. I decided to give 1440 a try & I've not been disappointed.

Now is definitely the time to save big on a highly sophisticated computerized telescope as the Unistellar eQuinox is now $1000 off on their website. The deal ends Sept. 30.
he bright moon passes by Saturn tonight, coinciding with the moon's closest approach to Earth.
Currently in a waxing gibbous phase, the moon will appear near Saturn on the evenings of September 7th and 8th. However, while Saturn currently shines brightly at a +0.4 magnitude, the moon's glow may make it difficult to spot the ringed planet — especially as the moon reaches perigee.

The newly discovered planets orbit an ultracool dwarf star and one is in the habitable zone, making it a prime target for further investigation. Here's what we know.
Earth's sister planet Venus is experiencing a bout of extreme space weather this week after a giant sunspot, not visible from Earth, expelled an enormous plasma burst toward the scorching-hot planet.
NASA's Artemis 1 moon rocket is staying at the launch pad, at least for now.
Artemis 1 will use NASA's new Space Launch System (SLS) megarocket to send an uncrewed Orion capsule to lunar orbit and back. NASA attempted to launch the epic mission on Saturday (Sept. 3) but stood down when it couldn't troubleshoot a leak of supercold liquid hydrogen (LH2) propellant in time for liftoff.
Devon Island is one of the most radio-quiet places in the northern hemisphere, a perfect place for the Haughton-Mars Project to conduct the EDGES experiment. Here's how it works.
The U.S. Air Force conducted an early-morning suborbital test of an unarmed Minuteman III intercontinental ballistic missile, or ICBM, on Wednesday (Sept. 7).
This nighttime photo of the launch is just stunning.
