‘Upside-down planet’ reveals new method for studying binary star systems

What looked at first like a sort of upside-down planet has instead revealed a new method for studying binary star systems, discovered by a University of Washington student astronomer.

Bacteria get new badge as planet's detoxifier

A study published this week in PLOS ONE authored by Dr. Henry Sun and his postdoctoral student Dr. Gaosen Zhang of Nevada based research institute DRI provides new evidence that Earth bacteria can do something that is quite unusual.

Water detected on planet outside our solar system

Water has been detected in the atmosphere of a planet outside our solar system with a new technique that could help researchers to learn how many planets with water, like Earth, exist throughout the universe.

Astronomers discover planet that shouldn't be there

An international team of astronomers, led by a University of Arizona graduate student, has discovered the most distantly orbiting planet found to date around a single, sun-like star. It is the first exoplanet – a planet outside of our solar system – discovered at the UA.

Ozone hole might slightly warm our planet

A lot of people mix up the ozone hole and global warming, believing the hole is a major cause of the world’s increasing average temperature. Scientists, on the other hand, have long attributed a small cooling effect to the ozone shortage in the hole.

Scientists outline long-term sea-level rise in response to warming of planet

A new study estimates that global sea levels will rise about 2.3 meters, or more than seven feet, over the next several thousand years for every degree (Celsius) the planet warms.

This black hole is having a light snack

Astronomers are observing a black hole that woke up from a decades-long slumber to feed on a low-mass object - either a brown dwarf or a giant planet - that strayed too close.

Young stars and planets grow up together

Astronomers have shed further light on the mysterious process of how young stars and their planetary systems form.

Fomalhaut b regains planetary status

The nearby star Fomalhaut does host a massive exoplanet after all, say NASA scientists following a second look at Hubble data.

Vesta 'stretch marks' suggest it's a stunted planet

Enormous troughs that encircle the asteroid Vesta may be faults that formed when another asteroid smacked into its south pole, and indicate that it has the same type of interior as a planet.

Life's building blocks found around sun like our own

Sugar molecules have for the first time been spotted in the gas surrounding a young sun-like star.

Planet-eating star points to our own future

NASA scientists have caught a star in the act of swallowing up a planet, the first time such a thing has ever been observed.

Habitable planet has three suns

Astronomers have discovered a potentially habitable planet right on our doorstep - just 22 light years away.

Double star could host habitable planet

Planets with two suns - like Star Wars' Tatooine - could really be habitable, astrophysicists have concluded - and they say they know where to look.

Lutetia asteroid is failed planet

New observations of the Lutetia asteroid have revealed that it's a planet that never properly formed.

Planet evaporates under fierce X-ray blasts

Astronomers at the Chandra X-ray observatory say they've observed a planet so close to an active star that it's evaporating.

'Invisible' planet detected

Astronomers have for the first time discovered a previously unknown exoplanet through its effects on another planet in the system.

Astronomers discover a planet made of diamond

An international team of scientists has discovered a planet made of diamond after first detecting a pulsar using the Parkes and Lovell radio telescopes.

Billions of 'orphan planets' wander alone in space

Hundreds of billions of isolated planets are believed to be floating alone in space, following an international survey of the sky.

Astronomers see birth of new exoplanet

Astronomers believe they have found a planet in the process of formation, clearing a path in the natal disc surrounding a young star.
