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.....»»
Examining how stellar threats impact the habitable zone of exoplanets
When we think of exoplanets that may be able to support life, we home in on the habitable zone. A habitable zone is a region around a star where planets receive enough stellar energy to have liquid surface water. It's a somewhat crude but helpful fir.....»»
How many additional exoplanets are in known systems?
One thing we've learned in recent decades is that exoplanets are surprisingly common. So far, we've confirmed nearly 6,000 planets, and we have evidence for thousands more. Most of these planets were discovered using the transit method. though there.....»»
Hubble and Webb probe surprisingly smooth disk around Vega
In the 1997 movie "Contact," adapted from Carl Sagan's 1985 novel, the lead character scientist Ellie Arroway (played by actor Jodi Foster) takes a space-alien-built wormhole ride to the star Vega. She emerges inside a snowstorm of debris encircling.....»»
Taiwan cleans up after Typhoon Kong-rey leaves two dead
Workers cleared fallen trees and shop owners swept up debris in Taiwan on Friday after one of the biggest typhoons to hit the island in decades claimed at least two lives......»»
Laser measurements help track space debris and observe water masses
What do the Earth's gravitational field and the trajectories of satellites and space debris have in common? The Earth's gravitational field influences the orbits of our companions in space, while the changes in the orbits in turn allow conclusions to.....»»
NASA telescopes discover brown dwarf protoplanetary disks in the Orion Nebula
Newborn stars are surrounded by disks of gas and dust within which planets are born, known as protoplanetary disks. In the Orion Nebula, the brightest and most massive stars emit intense ultraviolet radiation that illuminates protoplanetary disks, al.....»»
One of the last floppy disk industries is finally modernizing
The Muni Metro in San Francisco was recently approved for an update that would transition it from a control system using floppy disks to a more modern system......»»
Plans to Destroy the International Space Station Preview a Bigger Orbital Junk Problem
A special spacecraft will guide the space station through Earth’s atmosphere, but what about other large pieces of space debris?.....»»
Tropical storm leaves towns submerged, 76 dead in Philippines
Homeowners in the northern Philippines used spades and rakes to clear out debris left by Tropical Storm Trami on Friday while rescuers trawled through thick mud looking for the missing as the death toll rose to 76......»»
Did some of Earth"s water come from the solar wind?
The source of Earth's water is an enduring mystery that extends to exoplanets and the notion of habitability. In broad terms, Earth's water was either part of the planet from the beginning of its formation in the solar nebula or delivered later, mayb.....»»
San Francisco to pay $212 million to end reliance on 5.25-inch floppy disks
Muni Metro also plans to ditch super-slow loop cable communication system. The San Francisco Municipal Transportation Agency (SFMTA) board has agreed to spend $212 million to get.....»»
Moonlight may hamper views of the Orionid meteor shower, debris of Halley"s comet
The Orionids—one of two annual meteor showers from Halley's comet—peak early Monday. A bright waning moon may make them difficult to spot......»»
ULA is examining debris recovered from Vulcan rocket’s shattered booster nozzle
"I’m pretty confident... that we’ll get to the bottom of this pretty quickly and move on.” When the exhaust nozzle on one of the Vulcan rocket's strap-on boosters failed sho.....»»
What do planet formation and badminton have in common?
Dust grains in protoplanetary disks align via the same aerodynamics as the sport. The birth of a planet starts with a microscopic grain floating in a protoplanetary disk, a swirli.....»»
Where to find Ancient Debris and Netherite Ingots in Minecraft
Nether Ingots can help create some very strong tools and armor, but they can be tricky to make. If you're unsure how to craft this material, we can help you!.....»»
Exoplanet discovered in a binary system could explain why red dwarfs form massive planets
In recent years, the number of known extrasolar planets (aka. exoplanets) has grown exponentially. To date, 5,799 exoplanets have been confirmed in 4,310 star systems, with thousands more candidates awaiting confirmation. What has been particularly i.....»»
Why Hurricane Milton Turned the Sky Purple
The strange, apocalyptic skies during the storm reveal how light behaves in the atmosphere when it’s filled with an unusual amount of water vapor, dust, and debris......»»
Hurricane Milton spawns destructive, deadly tornadoes before making landfall
Multiple powerful tornadoes ripped across Florida hours before Hurricane Milton made landfall Wednesday, tearing off roofs, overturning vehicles and sucking debris into the air as the black V-shaped columns moved through......»»
X-rays advance understanding of Earth"s core-mantle boundary and super-Earth magma oceans
Researchers at the Department of Energy's SLAC National Accelerator Laboratory have revealed new details about Earth's core-mantle boundary and similar regions found in exoplanets......»»
Investigating the statistical likelihood of triple star systems hosting exoplanets
Why is it important to search for exoplanets in triple star systems and how many can we find there? This is what a recent study accepted by Astrophysics & Space Science hopes to address after a pair of researchers from the University of Texas at Arli.....»»
