 re: Senator Padilla

"During a press conference today held at the FBI’s Los Angeles Field Office, Senator Alex Padilla was detained by members of the U.S. Secret Service assigned to Secretary Noem’s detail when he became disruptive while formal remarks were being delivered. Secret Service Agents were assisted by FBI Police who are in Los Angeles at this time.  Senator Padilla did not identify himself and was not wearing his senate security pin.

#NASARoman will soon make particular types of gravitational lenses far more common, pinpointing over 160,000 of them. (To date, we only know of hundreds.) A team plans to study these objects to refine our studies of dark matter: bit.ly/3SyNJDy 🔭 🧪 ☄️
Graphic labeled, Simulations of Gravitationally Lensed Galaxies in a Roman Space Telescope Image, shows a simulated Roman Space Telescope image within the detectors of its Wide Field Instrument at center as a 3-by-6 array of squares. Within each square are a range of white pinpoints against a black background, some slightly larger than others, but all tiny. There are four pullouts from the main image, shown as four boxes, two in a column at left and two at right. Each pullout shows a magnified view of the tiny dot it points to. All four pullouts show simulated gravitational lenses, which look like a thick white dot at center surrounded by fuzzy, slightly incomplete circles that are semi-transparent.

🧵 Here is a cosmic delight: LBN 867, dubbed the Raspberry Nebula although its overall structure is more like an onion! In fact, this fascinating H II region, located in the constellation Orion, contains three different objects within its structure! ➡️ noirlab.edu/public/image... 🔭 🧪 #science
The image features the Raspberry Nebula (LBN 867), located in the constellation of Orion. Imagine a vast cosmic cloud stretching into space, with a complex structure that resembles an onion due to its multiple layers. At its center shines a bright star, HD 34989, which emits an intense light, similar in brightness to the planet Uranus as seen from Earth, creating a bright focal point in the heart of the nebula. The nebula itself has a vivid red glow, like a scarlet bloom, due to the ionization of hydrogen gas glowing under the influence of the central star. Around HD 34989, a thin halo of blue-white light can be seen, a delicate reflection of starlight on interstellar dust, forming the reflection nebula vdB 38. This bluish halo contrasts with the dominant red, adding a cooler, more nuanced touch of color. The overall image is a mix of bright red hues and hints of pale blue, with the central star standing out like a bright beacon in a sea of ​​cosmic clouds.

Found a baby songbird? Here's a newly updated chart!
A chart that explains what to do If You Find A Baby Songbird Out Of The Nest. Is it hurt or did a cat get it? (Cat bites & scratches cause deadly infections.) or, Has a person kept it for over a day, given it food or water, or gotten it wet? If yes, Contact a licensed wildlife rehabilitator 
or wildlife care center near you. An online search can help. If no, what does it look like? Eyes not yet open. You have a hatchling. It's very young. Eyes open; feathers few & may be in tube-like sheaths. You have a nestling. Feathered; awkwardly hops or flutters; tail & wings short. You have a fledgling. Many sharp teeth; large claw on second toe. You have a velociraptor. If a hatchling or nestling, can you see the nest? If yes, Return it to its nest. The parents won’t care if they can smell you. If no, Make a nest from a basket & dried grass. Wire it to a tree. (Note: A few species, like Juncos, need a nest on the ground.) If a fledgling, is it in immediate danger? If yes, carefully move it to a safer spot nearby. If no, DO NOT INTERVENE! Though the bird looks awkward, it’s in a natural stage & the parents are still feeding it. If a velociraptor, has it seen you? If yes, back away slowly. Do not show fear. If no, run. Watch for others that may attack from the sides. FYI: Some babies (eg. swifts, most woodpeckers) only sit on the ground if in trouble. When in doubt, keep watch & contact a wildlife rehabilitator if needed!

In 1989, a team at STScI published the Guide Star Catalog to aid in accurately pointing the telescope. Collecting data from stars and other targets requires knowledge of their precise location in the sky, such as the stars near the Whirlpool Galaxy: bit.ly/4lk1nHR 🔭 🧪
