Exoplanets in debris disks
Debris disks around main-sequence stars are tenuous belts of dust thought to be produced when asteroids or other planetesimals collide and fragment. They are common: more than about a quarter of all main-sequence stars have debris disks and, since th.....»»
Influence of a black hole"s spin: First evidence of precession in ultraluminous accretion disks
Gas swirls around a black hole due to its intense gravity, forming an accretion disk. These accretion disks, being among the most efficient energy conversion mechanisms in the universe, emit light and plasma jets. When a black hole spins on its axis,.....»»

More than 60 dead from storm Helene as rescue, cleanup efforts grow
Rescuers struggled on Saturday with washed-out bridges and debris-strewn roads in the search for survivors of devastating Storm Helene, which killed at least 63 people across five states and caused massive power outages......»»
This Roborock smart vacuum cleans for up to seven weeks — just $330
The Roborock Q5 Max+ robot vacuum comes with a self-emptying dock that holds up to seven weeks' worth of dirt and debris. It's on sale from Amazon at $120 off......»»
Exoplanets could be hiding their atmospheres
Most of the exoplanets we've discovered orbit red dwarf stars. This isn't because red dwarfs are somehow special, simply that they are common. About 75% of the stars in the Milky Way are red dwarfs, so you would expect red dwarf planets to be the mos.....»»
Citizen science collaboration yields precise data on exoplanet WASP-77 A b
A planet swings in front of its star, dimming the starlight we see. Events like these, called transits, provide us with bounties of information about exoplanets—planets around stars other than the sun. But predicting when these special events occur.....»»
Could interstellar quantum communications involve Earth or solve the Fermi paradox?
Thus far, the search for extraterrestrial intelligence (SETI) has used strategies based on classical science—listening for radio waves, telescopes watching for optical signals, telescopes in orbit scouring light from the atmospheres of exoplanets,.....»»
Astronomers discover new feature in exoplanet distribution that"s between the Neptunian Desert and Savanna
Astronomers have uncovered the "Neptunian Ridge," a newly identified feature in the distribution of exoplanets. This discovery, led by an international team including members of the University of Geneva, The NCCR PlanetS and the Centro de Astrobiolog.....»»
Old satellite to burn up over Pacific in "targeted" re-entry first
After 24 years diligently studying Earth's magnetic field, a satellite will mostly burn up over the Pacific Ocean on Sunday during a "targeted" re-entry into the atmosphere, in a first for the European Space Agency as it seeks to reduce space debris......»»
AI shines a new light on exoplanets
Researchers from LMU, the ORIGINS Excellence Cluster, the Max Planck Institute for Extraterrestrial Physics (MPE), and the ORIGINS Data Science Lab (ODSL) have made an important breakthrough in the analysis of exoplanet atmospheres......»»
Managing space debris through space law
It's becoming increasingly crowded in the orbits around Earth that are popular for space travel. And that's not just due to satellites—there's also more waste material, which is compromising safety. Ph.D. candidate Zhuang Tian is conducting researc.....»»
Amateur Scientist: Detect Cosmic Dust & Space Debris
Tweak the Make: Twilight photometer to detect micrometeors and orbital junk 400 miles high. The post Amateur Scientist: Detect Cosmic Dust & Space Debris appeared first on Make: DIY Projects and Ideas for Makers......»»
How vegetation could impact the climate of exoplanets
The term "habitable zone" is a broad definition that serves a purpose in our age of exoplanet discovery. But the more we learn about exoplanets, the more we need a more nuanced definition of habitable......»»
Naval Research Laboratory"s LARADO instrument to detect lethal orbital debris, integrated on STP satellite
U.S. Naval Research Laboratory's (NRL) Lightsheet Anomaly Resolution and Debris Observation (LARADO) instrument was successfully integrated and tested on the Space Test Program Satellite 7 (STPSat-7) spacecraft at National Aeronautics and Space Admin.....»»
Supercomputer simulations reveal the nature of turbulence in black hole accretion disks
Researchers at Tohoku University and Utsunomiya University have made a breakthrough in understanding the complex nature of turbulence in structures called accretion disks surrounding black holes, using state-of-the-art supercomputers to conduct the h.....»»
After wildfires, mudslides come: Fighting the impact of climate change on rural communities
It took more than 25 years for Rhonda MacDonald and her family to transform their 41-hectare property on the Shackan Indian Band Lands, south of Merritt, BC, into a vibrant business and homestead—but a massive 2022 debris flow changed everything in.....»»
Antarctica vulnerable to invasive species hitching rides on plastic and organic debris, oceanographic model shows
Antarctica's unique ecosystems could be threatened by the arrival of non-native marine species and marine pollution from Southern Hemisphere landmasses, new oceanographic modeling shows......»»
Earth-like exoplanets might be in short supply for the Habitable Worlds Observatory
How common are Earth-like exoplanets—also called exo-Earths—and which exoplanetary systems should we target to find them?.....»»
Exoplanets may contain more water than previously thought
We know that the Earth has an iron core surrounded by a mantle of silicate bedrock and water (oceans) on its surface. Science has used this simple planet model until today for investigating exoplanets—planets that orbit another star outside our sol.....»»
