Planet

Scientists now believe water worlds are far more common, but these exoplanets in the galaxy with water may have them mixed with rock or underground rather than as surface oceans.

This information about charcoal formed by asteroid impacts can help give a better idea about the range of how bad such an impact could be.

The two images were taken by the observatory's Near-Infrared Camera (NIRCam), which uses three infrared filters to capture hidden details of the planet.

A passing star, known as a stellar flyby, could — in theory — cause changes in Neptune's atmosphere that could — in theory —eventually lead to planets colliding into each other.

The two studies described a new method of clustering types of minerals together or separating them into new species based on their origins.

The space agency launched two missions to gather measurements of ultraviolet light in order to understand what makes a planet's atmosphere habitable.

Mercury, Venus, Mars, Jupiter and Saturn will be visible every morning until the end of June in an alignment not seen since 1864.

Scientists believe the brightness of the star at the center of the system and its proximity to Earth could provide new insight into the planets and their atmospheres.

Using observations from the Hubble Space Telescope, the NASA Infrared Telescope Facility, and the Gemini North telescope, an international team of researchers look for answers.

Brown dwarfs are cosmic objects often described as being between a planet and a star. However, they are very hard to detect. In fact, for around three decades, only 40 brown dwarfs have been imaged.
