Many gas giant exoplanets waiting to be discovered

There is an as-yet-unseen population of Jupiter-like planets orbiting nearby Sun-like stars, awaiting discovery by future missions like NASA's WFIRST space telescope, according to new models of gas giant planet formation ...

Measuring stellar oscillations with Kepler

The Kepler satellite is famous for its discovery of thousands of exoplanets by continuously and meticulously measuring the brightnesses of over half-a-million stars for the signatures of transiting exoplanets. Less well known ...

Newly discovered giant planet slingshots around its star

Astronomers have discovered a planet three times the mass of Jupiter that travels on a long, egg-shaped path around its star. If this planet were somehow placed into our own solar system, it would swing from within our asteroid ...

Mrk 1498 hosts a young and obscured AGN, study finds

An international team of astronomers has found that the giant radio galaxy (GRG) Mrk 1498 has a more complex nuclear structure than previously thought. By analyzing multi-wavelength observations of Mrk 1498, a young and obscured ...

Image: Hubble's portrait of star's gaseous glow

Although it looks more like an entity seen through a microscope than a telescope, this rounded object, named NGC 2022, is certainly not algae or tiny, blobby jellyfish. Instead, it is a vast orb of gas in space, cast off ...

New space discovery sheds light on how planets form

Researchers at Dartmouth College have discovered a planet orbiting one of the brightest young stars known, according to a study published in the journal The Astrophysical Journal Letters. Aged at approximately 45 million ...

Old at heart: A solution to red giants' age paradox

Four years ago, several red giant stars were discovered to pose a paradox: even though they are built from very old stellar material, their large masses indicate a clearly younger age. Scientists from the Max Planck Institute ...
