“This connection links two vastly different forms of light over an energy range spanning a factor of 10 billion.”
Using data from from NASA’s Wide-field Infrared Survey Explorer (WISE) and Fermi Gamma-ray Space Telescope, astronomers studying distant galaxies powered by monster black holes have uncovered an unexpected link between two very different wavelengths of the light they emit, the mid-infrared and g

“In the coming decades, we will be seeing the significant human health consequences from these extreme events in a changing climate.”
Newly published research identifies the western U.S. counties with the highest risk of exposure to pollution from wildfires. Wildfires threaten more than land and homes. The smoke they produce contains fine particles (PM2.5) that can poison the air for hundreds of miles. Air pollution from th

“What we take for granted on this planet, such as oceans and continents, would not exist if the internal temperature of Earth had not been in a certain range, and this means that the beginning of Earth’s history cannot be too hot or too cold.”
New research from Yale University suggests that simply being in the habitable zone isn’t sufficient to support life. A planet also must start with an internal temperature that is just right. The search for habitable, alien worlds needs to make room for a second “Goldilocks,” according to a Ya

In the years 1970-75 published the German professor Hoimar von Ditfurth books in which he considered this to be proven that no life would arise without internal heat. The warmth of our sun would not be enough to sustain life.
In den Jahren 1970-75 veröffentlichte der deutsche Professor Hoimar von Ditfurth Bücher in denen er dies als erwiesen betrachtete, dass kein Leben entstehen würde, ohne innere Wärme. Die Wärme unserer Sonne würde nicht ausreichen, Leben zu erhalten.

“This planet might be the first time we detect oxygen on a rocky planet outside the solar system.”
New research from the Harvard-Smithsonian Center for Astrophysics reveals that the Venus-like Exoplanet GJ 1132b might possess a thin, oxygen atmosphere - but no life due to its extreme heat. The distant planet GJ 1132b intrigued astronomers when it was discovered last year. Located just 39 l

“The shock injected – meaning it pushed – electrons from outer regions of the magnetosphere deep inside the belt, and in that process, the electrons gained energy.”
New research details how a shockwave created by the driving force of a coronal mass ejection from the sun – struck the outermost radiation belt, triggering the greatest geomagnetic storm of the preceding decade. Our planet is nestled in the center of two immense, concentric doughnuts of power

The new paper marks the dawn of a new age in imaging and analyzing extrasolar planetary systems.
Using the ALMA submillimeter array, astronomers image the disk around HR8799 with a spatial scale as small as only thirty-two au, enough to probe the inner zones of the disk. Planets develop from the dusty placental disk of material that surrounds a star after it begins to shine. The dust in

(It has been reported that Olympic runner Florence Griffith Joyner, who died suddenly in 1998, had this condition.)
Yale scientists have discovered a new and effective therapy for cerebral cavernous malformations. A team of researchers led by Yale professor of pathology Wang Min have pinpointed a marker that contributes to a chronic condition affecting the brain. Known as cerebral cavernous malformations,

NGC 5264 clearly possesses an irregular shape — unlike the more common spiral or elliptical galaxies — with knots of blue star formation.
This new Hubble image captures the glow of distant stars within NGC 5264, a dwarf galaxy located just over 15 million light-years away in the constellation of Hydra (The Sea Serpent). Dwarf galaxies like NGC 5264 typically possess around a billion stars — just one per cent of the number of st

“To enable a deeper understanding of biology, we engineered human cells that are able to report on their own history based on genetically encoded recorders.”
Newly published research details how biological engineers from MIT developed a way to record complex histories in the DNA of human cells, allowing them to retrieve “memories” of past events by sequencing the DNA. This analog memory storage system — the first that can record the duration and/o

This means that the supernova responsible for this object would simply have appeared too faint to be seen with the naked eye in 386 CE, leaving the nature of the observed 386 CE event a mystery.
New Chandra data of the supernova remnant G11.2-0.3 raise new questions about the timing of its origin. Chandra observations show that dense gas clouds lie along the line of sight between Earth and G11.2-0.3, meaning that the supernova explosion would have been too faint to be seen with the nake

“The success of these observations depended on both SOFIA’s ability to observe wavelengths inaccessible from the ground, and the large size of its telescope, which provided a more detailed map than would have been possible with smaller telescopes.”
Using data from NASA’s Stratospheric Observatory for Infrared Astronomy and other observatories, astronomers reveal how a particular type of organic molecules, the raw materials for life – could develop in space. This information could help scientists better understand how life could have develo

The exploding star was a white dwarf located in the Large Magellanic Cloud, one of our nearest neighboring galaxies.
This newly released Hubble image shows the aftermath of an exploding star that was located in the Large Magellanic Cloud. Several thousand years ago, a star some 160,000 light-years away from us exploded, scattering stellar shrapnel across the sky. The aftermath of this energetic detonation i
