A deep infrared view of the Orion Nebula reveals an abundance of faint brown dwarfs and an unexpected number of planetary-mass objects, key elements in studies of star formation and the environments that produce them.
Astronomers have discovered evidence of three more gas giant worlds orbiting a star already known to host a ‘hot Jupiter’ in an extremely close orbit. The observations raise new questions about how solar systems form.
Astronomers struggling to understand why an unusual stars periodically fades and brightens have collected X-ray observations indicating it may be due to the catastrophic collision of two infant planets.
By measuring the motion of carbon monoxide molecules in a protoplanetary disc, two teams of astronomers have found three planets lurking in the rings of dust around a star just a few million years old.
Astronomers have detected microwave emissions from three protoplanetary disks that apparently are generated by vast clouds of tiny, spinning nanodiamonds, tiny motes of carbon found in star-forming regions
