Can Life Survive a Star's Death? Webb Telescope Can Reveal the Answer

When stars like our sun die, all that remains is an exposed core -- a white dwarf. A planet orbiting a white dwarf presents a promising opportunity to determine if life can survive the death of its ...

Enormous Planet Quickly Orbiting a Tiny, Dying Star

Thanks to a bevy of telescopes in space and on Earth -- and even a pair of amateur astronomers in Arizona -- astronomers have discovered a Jupiter-sized planet orbiting at breakneck speed around a ...

Scientist Searches for Stellar Phosphorus to Find Potentially Habitable Exoplanets

A scientist has identified stellar phosphorus as a probable marker in narrowing the search for life in the cosmos. She has developed techniques to identify stars likely to host exoplanets, based on ...

A Warm Jupiter Orbiting a Cool Star

A planet observed crossing in front of, or transiting, a low-mass star has been determined to be about the size of ...

Carbon-Rich Exoplanets May Be Made of Diamonds

Astronomers have determined that some carbon-rich exoplanets, given the right circumstances, could be made of diamonds and ...

Meteorites Show Transport of Material in Early Solar System

New studies of a rare type of meteorite show that material from close to the Sun reached the outer solar system even as the planet Jupiter cleared a gap in the disk of dust and gas from which the ...

Peculiar Planetary System Architecture Around Three Orion Stars Explained

In our Solar System, the eight planets and many other minor objects orbit in a flat plane around the Sun; but in some distant systems, planets orbit on an incline -- sometimes a very steep one. New ...

Fifty New Planets Confirmed in Machine Learning First

Fifty potential planets have had their existence confirmed by a new machine learning ...

Unveiling Rogue Planets With NASA's Roman Space Telescope

New simulations show that NASA's Nancy Grace Roman Space Telescope will be able to reveal myriad rogue planets -- freely floating bodies that drift through our galaxy untethered to a ...

NASA's Planet Hunter Completes Its Primary Mission

NASA's TESS has completed its primary mission, imaging about 75% of the starry sky during a two-year-long survey. TESS has found 66 new planets, nearly 2,100 candidates, and much ...

Hubble Uses Earth as Proxy for Identifying Oxygen on Potentially Habitable Exoplanets

Taking advantage of a total lunar eclipse, Hubble used the Moon as a mirror to study sunlight that had passed through Earth's atmosphere. As a result, Hubble detected Earth's own brand of ...

Surprisingly Dense Exoplanet Challenges Planet Formation Theories

New detailed observations reveal a young exoplanet, orbiting a young star in the Hyades cluster, that is unusually dense for its size and age. Weighing in at 25 Earth-masses, and slightly smaller ...

Planet Found Orbiting Small, Cool Star

Precision measurements made with the VLBA have revealed that a small, cool star 35 light-years from Earth is orbited by a Saturn-sized planet once every 221 ...

ALMA Captures Stirred-Up Planet Factory

Planet-forming environments can be much more complex and chaotic than previously expected. This is evidenced by a new image of the star RU Lup, made with the Atacama Large Millimeter/submillimeter ...

Surprising Number of Exoplanets Could Host Life

A new study shows other stars could have as many as seven Earth-like planets in the absence of a gas giant like ...

First Ever Image of a Multi-Planet System Around a Sun-Like Star Captured by ESO Telescope

The European Southern Observatory's Very Large Telescope has taken the first ever image of a young, Sun-like star accompanied by two giant exoplanets. Images of systems with multiple exoplanets ...

'Lost' World's Rediscovery Is Step Towards Finding Habitable Planets

The rediscovery of a lost planet could pave the way for the detection of a world within the habitable 'Goldilocks zone' in a distant solar ...

Artificial Intelligence Predicts Which Planetary Systems Will Survive

An astrophysicist has found a new method for determining the long-term stability of planetary configurations that is up to 100,000 times faster than the previous approach. This breaks the ...

Unprecedented Ground-Based Discovery of 2 Strongly Interacting Exoplanets

Several interacting exoplanets have already been spotted by satellites. But a new breakthrough has been achieved with, for the first time, the detection directly from the ground of an extrasolar ...
