NASA Astronomy Picture of the Day:

These dark pillars may look destructive, but they are creating stars. This pillar-capturing picture of the Eagle Nebula combines visible light exposures taken with the Hubble Space Telescope with infrared images taken with the James Webb Space Telescope to highlight evaporating gaseous globules (EGGs) emerging from pillars of molecular hydrogen gas and dust. The giant pillars are light years in length and are so dense that interior gas contracts gravitationally to form stars. At each pillar's end, the intense radiation of bright young stars causes low density material to boil away, leaving stellar nurseries of dense EGGs exposed. The Eagle Nebula, associated with the open star cluster M16, lies about 7000 light years away. Jigsaw Challenge: Astronomy Puzzle of the Day

"A growing number of students in public schools – right now, about 15% of them – are eligible for special education services. These services include specially designed instruction for students with autism, learning or physical disabilities, or traumatic brain injuries. But going into the current school year, more than half of U.S. public schools anticipate being short-staffed in special education. More at The Conversation ➜

NASA Astronomy Picture of the Day:

The tails of Comet Tsuchinshan-ATLAS were a sight to behold. Pictured, C/2023 A3 (Tsuchinshan–ATLAS) was captured near peak impressiveness last week over the Eastern Sierra Mountains in California, USA. The comet not only showed a bright tail, but a distinct anti-tail pointing in nearly the opposite direction. The globular star cluster M5 can be seen on the right, far in the distance. As it approached, it was unclear if this crumbling iceberg would disintegrate completely as it warmed in the bright sunlight. In reality, the comet survived to become brighter than any star in the night (magnitude -4.9), but unfortunately was then so nearly in front of the Sun that it was hard for many casual observers to locate. Whether Comet Tsuchinshan-Atlas becomes known as the Great Comet of 2024 now depends, in part, on how impressive incoming comet C/2024 S1 (ATLAS) becomes over the next two weeks.

NASA Astronomy Picture of the Day:

Is our universe haunted? It might look that way on this dark matter map. The gravity of unseen dark matter is the leading explanation for why galaxies rotate so fast, why galaxies orbit clusters so fast, why gravitational lenses so strongly deflect light, and why visible matter is distributed as it is both in the local universe and on the cosmic microwave background. The featured image from the American Museum of Natural History's Hayden Planetarium Space Show Dark Universe highlights one example of how pervasive dark matter might haunt our universe. In this frame from a detailed computer simulation, complex filaments of dark matter, shown in black, are strewn about the universe like spider webs, while the relatively rare clumps of familiar baryonic matter are colored orange. These simulations are good statistical matches to astronomical observations. In what is perhaps a scarier turn of events, dark matter -- although quite strange and in an unknown form -- is no longer thought to be the strangest source of gravity in the universe. That honor now falls to dark energy, a more uniform source of repulsive gravity that seems to now dominate the expansion of the entire universe. Explore Your Universe: Random APOD Generator

"When Anna Nusslock showed up at her local hospital 15 weeks pregnant and in severe pain earlier this year, she said, a doctor delivered devastating news: The twins she and her husband had so desperately wanted were not viable. Further, her own health was in danger, and she needed an emergency abortion to prevent hemorrhaging and infection.......Providence St. Joseph Hospital, in the small Northern California coastal city of Eureka, refused to provide the care she required because doctors could detect fetal "heart tones," Nusslock said".....  More at The National Catholic Reporter (NCR) ➜
