Hubble photo shows a cosmic cloud making its very own bright light

The legendary Hubble telescope captured an intriguing cosmic cloud — a cloud that makes its own light.

Called an "emissions nebula," it's a bright cloud whose gases get excited by radiation from nearby stars, and ultimately emit light. (In other words, this isn't starlight isn't being reflected off the gas.)

The right side of this image, however, is darkened by a great cloud of dust, which blocks light from reaching the Hubble Space Telescope.

Perseverance rover officially starts its big search for past life...with lasers

Zap.

After the Perseverance rover spent its first three months on Mars getting its bearings and serving as an observation post for the successful Ingenuity helicopter flights, NASA announced the robot has started its primary mission: seeking out past evidence of microbial life — should any have ever existed.

"The time has come: I’m switching from on-scene photographer to science investigator," NASA's Perseverance rover Twitter account posted this week. "Did this ancient lakebed ever have life? The tools I brought will help begin the hunt. I’m a bot on a mission."

The "hunt" largely means scouring the geological and chemical make-up of rocks in the Jezero Crater, a place NASA believes was "once flooded with water and was home to an ancient river delta." Primitive life could have potentially dwelled in these wet soils, like it does on Earth. Read more...

Wong's deep dive into the backend of Twitter suggests that a subscription tier called Twitter Blue will give paying users access to exclusive features, including better tools for organizing bookmarks and an "undo" button that makes it possible to recall tweets within a certain timeframe. Some of the alleged options appeared on a Twitter survey conducted in summer 2020, which asked users about which app features they'd be willing to pay for, if any.  Read more...

See the colossal James Webb Space Telescope unfurl its giant, golden mirrors

Engineers commanded the James Webb Space Telescope to unfurl its over 21-foot wide golden mirrors this week, and the crucial test succeeded.

The test, shown in the image below, was the last check on the sprawling telescope's moving parts under space-like conditions. James Webb, set to launch in Oct. 2021, is the largest, most powerful space telescope ever built. It's the next generation of space telescope, furthering the legendary observations made by the aging, over 30-year old Hubble telescope

After launching into space, Webb's 18 hexagonal mirrors will align to form a "single, precise mirror," NASA engineer Lee Feinberg said in a statement. "The primary mirror is a technological marvel," Feinberg said. Read more...

Tiffany Haddish tearfully reflects on the viral moment when she won her Grammy

Tiffany Haddish tearfully reflects on the viral moment when she won her Grammy

When Tiffany Haddish made Grammy history in March, becoming the only the second Black woman to win for Best Comedy Album, after Whoopi Goldberg in 1986, it turned into a whole Moment. That's because Haddish found out while she was filming with a group of kids for her CBS series, Kids Say the Darnedest Things. Her emotional reaction to the news captivated pretty much everyone who saw it.

Now, two months later, Haddish is still feeling the power of that moment. Stephen Colbert returned to the viral clip when Haddish appeared alongside Billy Crystal on A Late Show to support their new movie, Here Today.  As the camera cut back to the Grammy winner's video call she was in (joyful) tears once again.
