TESS discovers nine new "hot Jupiters"
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered nine new "hot Jupiter" exoplanets. One of the newly detected alien worlds is almost four times more massive than Jupiter. The finding was p.....»»
Astronomers discover two new super-Earths orbiting nearby stars
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected two new super-Earth exoplanets orbiting nearby M-dwarf stars. The newfound exoplanets, designated TOI-6002 b and TOI-5713 b, are two times la.....»»
Plants offer fruit to insects to disperse dust-like seeds, botanist discovers
Fruit exist to invite animals to disperse the swallowed seeds. A Kobe University research team found that plants targeting insects rather than birds or mammals for this service are more common than previously thought. These plants produce dust-like s.....»»
Machine learning discovers "hidden-gem" materials for heat-free gas separation
Chemical separation, including gas separation, is a common process that is required for manufacturing and research. It accounts for a whopping 15% of U.S. energy consumption and produces millions of tons of carbon emissions......»»
TIC 441725813 is a hybrid pulsating subdwarf star, study finds
Astronomers have employed NASA's Transiting Exoplanet Survey Satellite (TESS) to observe a subdwarf star designated TIC 441725813. In result, they found that TIC 441725813 is a hybrid hot B subdwarf pulsator. The discovery was detailed in a research.....»»
Is this how you get hot Jupiters?
When we think of Jupiter-type planets, we usually picture massive cloud-covered worlds orbiting far from their stars. That distance keeps their volatile gases from vaporizing from stellar heat, similar to what we're familiar with in our solar system......»»
Perseverance rover discovers rock with potential signs of ancient life
A vein-filled rock is catching the eye of the science team of NASA's Perseverance rover. Nicknamed "Cheyava Falls" by the team, the arrowhead-shaped rock contains fascinating traits that may bear on the question of whether Mars was home to microscopi.....»»
NASA rocket discovers new energization process in upper atmosphere
When it comes to discoveries about our upper atmosphere, it pays to know your surroundings......»»
NASA"s Curiosity rover discovers a surprise in a Martian rock
Scientists were stunned on May 30 when a rock that NASA's Curiosity Mars rover drove over cracked open to reveal something never seen before on the Red Planet: yellow sulfur crystals......»»
Astronomers spot a "highly eccentric" planet on its way to becoming a hot Jupiter
Hot Jupiters are some of the most extreme planets in the galaxy. These scorching worlds are as massive as Jupiter, and they swing wildly close to their star, whirling around in a few days compared to our own gas giant's leisurely 4,000-day orbit arou.....»»
Astronomers detect dozens of new pulsating white dwarfs
Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have detected 32 new bright pulsating DA white dwarfs of the ZZ Ceti subclass. The finding was reported in a research paper published July 9 on the pre-print server arXiv......»»
Telescope tag-team discovers 10 strange and exotic pulsars
Towards the center of our Milky Way galaxy, in the constellation Sagittarius, astronomers have discovered 10 monstrous neutron stars. These particular stars, called pulsars, reside together in globular cluster Terzan 5, a crowded home for hundreds of.....»»
Team discovers a new defense mechanism in bacteria
When confronted with an antibiotic, toxic substance, or other source of considerable stress, bacteria are able to activate a defense mechanism using cell-to-cell communication to "warn" unaffected bacteria, which can then anticipate, shield themselve.....»»
James Webb discovers the most distant galaxy ever observed
Researchers using James Webb have discovered the most distant known galaxy to date. It existed just a few hundred million years after the Big Bang......»»
TESS finds intriguing world sized between Earth and Venus
Using observations by NASA's TESS (Transiting Exoplanet Survey Satellite) and many other facilities, two international teams of astronomers have discovered a planet between the sizes of Earth and Venus only 40 light-years away. Multiple factors make.....»»
Desert locusts" jaws sharpen themselves, materials scientist discovers
Sharks lose teeth all their lives, replacing them in a kind of endless rotating Rolodex, while humans, of course, get only our two sets. Beavers' teeth, notoriously, grow all their lives and have to be worn down to prevent injury......»»
New Saturn-mass exoplanet detected by astronomers
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new Saturn-mass planet orbiting a solar-type star known as TOI-2447. The finding was reported in a research paper published May 12 on the.....»»
Potentially habitable "exo-Venus" with Earth-like temperature discovered
Astronomers have made the rare and tantalizing discovery of an Earth-like exoplanet 40 light-years away that may be just a little warmer than our own world. The new paper "Gliese 12 b, A Temperate Earth-sized Planet at 12 Parsecs Discovered with TESS.....»»
Study discovers distinct population of "troublemaker" platelet cells appear with aging
As people age, they become more prone to blood clotting diseases, when blood cells called platelets clump together when they don't need to and can cause major issues such as strokes and cardiovascular disease. For decades, scientists have studied why.....»»
Study discovers cellular activity that hints recycling is in our DNA
Although you may not appreciate them, or have even heard of them, throughout your body, countless microscopic machines called spliceosomes are hard at work. As you sit and read, they are faithfully and rapidly putting back together the broken informa.....»»
TESS discovers a rocky planet that glows with molten lava as it"s squeezed by its neighbors
UC Riverside astrophysicist Stephen Kane had to double-check his calculations. He wasn't sure the planet he was studying could be as extreme as it seemed......»»
