NASA’s TESS Finds Intriguing World Sized Between Earth, Venus – NASA Science

5 min read NASA’s Compact Infrared Cameras Enable New Science A new, higher-resolution infrared camera outfitted with a variety of lightweight filters could probe sunlight reflected off Earth’s upper atmosphere and surface, improve forest fire warnings, and reveal the molecular composition of other planets. The cameras use sensitive, high-resolution strained-layer superlattice sensors, initially developed at … Read more

Discovery Alert: An Earth-sized World and Its Ultra-cool Star – NASA Science

Discovery Alert: An Earth-sized World and Its Ultra-cool Star – NASA Science

The exoplanet SPECULOOS-3 b is about 55 light-years from Earth (really close when you consider the cosmic scale!) and nearly the same size. A year there, one orbit around the star, takes about 17 hours. The days and nights, though, may never end: The planet is thought to be tidally locked, so the same side, … Read more

NASA’s Webb Hints at Possible Atmosphere Surrounding Rocky Exoplanet – NASA Science

While 55 Cancri e is far too hot to be habitable, researchers think it could provide a unique window for studying interactions between atmospheres, surfaces, and interiors of rocky planets, and perhaps provide insights into the early conditions of Earth, Venus, and Mars, which are thought to have been covered in magma oceans far in … Read more

Breaking the Scaling Limits: New Ultralow-noise Superconducting Camera for Exoplanet Searches – NASA Science

Breaking the Scaling Limits: New Ultralow-noise Superconducting Camera for Exoplanet Searches – NASA Science

When imaging faint objects such as distant stars or exoplanets, capturing every last bit of light is crucial to get the most out of a scientific mission. These cameras must be extremely low-noise, and be able to detect the smallest quantities of light—single photons.  Superconducting cameras excel in both of these criteria, but have historically … Read more

That Starry Night Sky? It’s Full of Eclipses

That Starry Night Sky? It’s Full of Eclipses

And astronomers can, in a sense, “see” eclipses among other systems of planets orbiting their parent stars. In this case, the eclipse is a tiny drop in starlight as a planet, from our point of view, crosses the face of its star. That crossing, called a transit, can register on sensitive light sensors attached to … Read more

Discovery Alert: a Long Year for a ‘Cold Saturn’

Discovery Alert: a Long Year for a ‘Cold Saturn’

The decades-long hunt for exoplanets – planets around other stars – has so far yielded more than 5,500 that are confirmed to be scattered across the Milky Way, which likely contains hundreds of billions. But the prevailing detection method turns up relatively few “long period” planets, those with years lasting 50 days or more. This … Read more

NASA Astronomer Sees Power in Community, Works to Build More – NASA

Science is often portrayed as a solitary affair, where discoveries are made by lone geniuses toiling in isolation. But Dr. Natasha Batalha, an astronomer at NASA’s Ames Research Center in California’s Silicon Valley, says solving problems with the people around her is one of the best parts of her job.  “Oh, man, working with people … Read more

Discovery Alert: Glowing Cloud Points to a Cosmic Collision – NASA Science

Even within our own solar system, scientists have seen evidence of giant, planetary collisions from long ago. Remaining clues like Uranus’ tilt and the existence of Earth’s moon point to times in our distant history when the planets in our stellar neighborhood slammed together, forever changing their shape and place in orbit. Scientists looking outside … Read more
