Scientists zoom in on distant solar system. It"s teeming with water.
Astronomers used the ALMA telescope array to observe the developing solar system around the star HL Tauri, In this young disk of matter, they identified lots of water near a potentially-forming planet. Astronomers are excited about this one. Us.....»»
Scientists discover radiation from massive stars shapes planetary systems
How do planetary systems such as the solar system form? To find out, CNRS scientists taking part in an international research team studied a stellar nursery, the Orion Nebula, using the James Webb Space Telescope. By observing a protoplanetary disk n.....»»
Astronomers reveal a new link between water and planet formation
Researchers have found water vapor in the disk around a young star exactly where planets may be forming. Water is a key ingredient for life on Earth and is also thought to play a significant role in planet formation, yet until now, astronomers have n.....»»
Researchers find destruction of oceans" worth of water per month in Orion Nebula
An international team, including Western astrophysicists Els Peeters and Jan Cami, has found the destruction and re-formation of a large quantity of water in a planet-forming disk located at the heart of the Orion Nebula......»»

Newborn gas planets may be surprisingly flat, says new research
A new planet starts its life in a rotating circle of gas and dust, a cradle known as a protostellar disk. My colleagues and I have used computer simulations to show that newborn gas planets in these disks are likely to have surprisingly flattened sha.....»»

Dracula"s Chivito: New protoplanetary disk discovered with Pan-STARRS
By analyzing the images obtained with the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS), astronomers have serendipitously discovered a new protoplanetary disk located some 800 light years away. The finding was reported in a paper.....»»
A black hole has cleared out its neighborhood
We can't see them directly, but we know they're there. Supermassive black holes (SMBHs) likely dwell at the center of every large galaxy. Their overwhelming gravity draws material toward them, where it collects in an accretion disk, waiting its turn.....»»
How to delete a user on your Mac and free up disk space
If your Mac has unused accounts that are taking up disk space, there’s an easy way to delete them. Here's how you can remove those accounts in just a few steps......»»
Generating powerful optical vortices directly from a thin-disk laser oscillator
In recent years, optical vortices have attracted extensive attention in laser advanced manufacturing because of their annual intensity distribution and orbital angular momentum......»»

Stars travel more slowly at Milky Way"s edge: Galaxy"s core may contain less dark matter than previously estimated
By clocking the speed of stars throughout the Milky Way galaxy, MIT physicists have found that stars further out in the galactic disk are traveling more slowly than expected compared to stars that are closer to the galaxy's center. The findings raise.....»»
Gemini South captures twisted dusty disk of NGC 4753, showcasing the aftermath of past merger
The lenticular galaxy NGC 4753, captured by the Gemini South telescope, one half of the International Gemini Observatory operated by NSF's NOIRLab, is a truly remarkable object. Its prominent and complex network of dust lanes that twist around its ga.....»»
Webb data suggest many early galaxies were long and thin, not disk-like or spherical
Columbia researchers analyzing images from NASA's James Webb Space Telescope have found that galaxies in the early universe are often flat and elongated, like breadsticks—and are rarely round, like balls of pizza dough......»»
Planetesimals are buffeted by wind in their nebula, throwing debris into space: Study
Before planets form around a young star, the protosolar disk is populated with innumerable planetesimals. Over time, these planetesimals combine to form planets, and the core accretion theory explains how that happens. But before there are planets, t.....»»
Webb discovers dusty "cat"s tail" in Beta Pictoris System
Beta Pictoris, a young planetary system located just 63 light-years away, continues to intrigue scientists even after decades of in-depth study. It possesses the first dust disk imaged around another star—a disk of debris produced by collisions bet.....»»
