“Missing” Supernova Images Offer Measure of Universe’s Expansion
Astronomers have found two gravitationally lensed supernovae that are missing images. Those images' arrival will offer a measure of the universe's expansion.
The post “Missing” Supernova Images Offer Measure of Universe’s Expansion appeared first on Sky & Telescope.

Ribbon worms can grow to enormous lengths, and one named Baseodiscus the Eldest is showing how little we know about them—including how long they live
The Universe's Most Common Water is a Hot Mess
Inside the cores of ice giant planets, the pressure and temperature are so extreme that the water residing there transitions into a phase completely unfamiliar under the normal conditions of Earth. Known as “superionic water”, this form of water is a type of ice. However, unlike regular ice it’s actually hot, and also black. For decades, scientists thought that the superionic water in the core of Neptune and Uranus is responsible for the wild, unaligned magnetic fields that the Voyager 2 spacecraft saw when passing them. A series of experiments described in a paper published in Nature Communications by Leon Andriambariarijaona and his co-authors at the SLAC National Accelerator Laboratory and the Sorbonne provides experimental evidence of why exactly the ice causes these weird magnetic fields - because it is far messier than anyone expected.

Hubble Snaps Stellar Baby Pictures The Cepheus A region is home to a number of infant stars, including a protostar that is responsible for much of the region’s illumination. NASA, ESA, and R.

Newly developing stars shrouded in thick dust get their first baby pictures in these images from NASA’s Hubble Space Telescope. Hubble took these infant star snapshots in an effort to learn how massive stars form.
Protostars are shrouded in thick dust that blocks light, but Hubble can detect the near-infrared emission that shines through holes formed by the protostar’s jets of gas and dust. The radiating energy can provide information about these “outflow cavities,” like their structure, radiation fields, and dust content. Researchers look for connections between the properties of these young stars – like outflows, environment, mass, brightness – and their evolutionary stage to test massive star formation theories.
These images were taken as part of the SOFIA Massive (SOMA) Star Formation Survey, which investigates how stars form, especially massive stars with more than eight times the mass of our Sun.

The high-mass star-forming region Cepheus A hosts a collection of baby stars, including one large and luminous protostar, which accounts for about half of the region’s brightness. While much of the region is shrouded in opaque dust, light from hidden stars breaks through outflow cavities to illuminate and energize areas of gas and dust, creating pink and white nebulae. The pink area is an HII region, where the intense ultraviolet radiation of the nearby stars has converted the surrounding clouds of gas into glowing, ionized hydrogen.
Cepheus A lies about 2,400 light-years away in the constellation Cepheus.

Glittering much closer to home, this Hubble image depicts the star-forming region G033.91+0.11 in our Milky Way galaxy. The light patch in the center of the image is a reflection nebula, in which light from a hidden protostar bounces off gas and dust.

This Hubble image showcases the star-forming region GAL-305.20+00.21. The bright spot in the center-right of the image is an emission nebula, glowing gas that is ionized by a protostar buried within the larger complex of gas and dust clouds.

Shrouded in gas and dust, the massive protostar IRAS 20126+4104 lies within a high-mass star-forming region about 5,300 light-years away in the constellation Cygnus. This actively forming star is a B-type protostar, characterized by its high luminosity, bluish-white color, and very high temperature. The bright region of ionized hydrogen at the center of the image is energized by jets emerging from the poles of the protostar, which ground-based observatories previously observed.
