Astrophysicists predict Earth-like planet in star system only 16 light years away

Astrophysicists have predicted that an Earth-like planet may be lurking in a star system just 16 light years away. The team investigated the star system Gliese 832 for additional exoplanets residing between the two currently known alien worlds in this system. Their computations revealed that an additional Earth-like planet with a dynamically stable configuration may be residing at a distance ranging from 0.25 to 2.0 astronomical unit (AU) from the star.

Exoplanet shines with glowing water atmosphere

Scientists have found compelling evidence for a stratosphere on an enormous planet outside our solar system. The planet's stratosphere -- a layer of atmosphere where temperature increases with higher altitudes -- is hot enough to boil iron.

NASA's Juno Spacecraft Spots Jupiter's Great Red Spot

Images of Jupiter's Great Red Spot reveal a tangle of dark, veinous clouds weaving their way through a massive crimson oval. The JunoCam imager aboard NASA's Juno mission snapped pics of the most iconic feature of the solar system's largest planetary inhabitant during its July 10 flyby.

Jupiter: Atmosphere and aurora in unprecedented detail

Subaru Telescope images reveal weather in Jupiter's atmosphere in the mid-infrared. High-resolution thermal imaging of Jupiter is providing information that extends and enhances the information that the Juno mission is gathering in its unprecedented mission to probe that planet's interior and deep atmospheric structure together with details of the magnetosphere and its auroral interactions with the planet.

The Bee-Zed asteroid orbits in the opposite direction to planets

In our solar system, an asteroid orbits the Sun in the opposite direction to the planets. It takes 12 years to make one complete orbit around the Sun. Researchers have developed a general theory on retrograde co-orbitals and retrograde orbital resonance.

Hubble's tale of two exoplanets: Nature vs. nurture

Is it a case of nature versus nurture when it comes to two 'cousin' exoplanets? In a unique experiment, scientists used NASA's Hubble Space Telescope to study two 'hot Jupiter' exoplanets. Because these planets are virtually the same size and temperature, and orbit around nearly identical stars at the same distance, the team hypothesized that their atmospheres should be alike. What they found surprised them.

Extreme Jupiter weather and magnetic fields

New observations about the extreme conditions of Jupiter's weather and magnetic fields by astronomers have contributed to the revelations and insights coming from the first close passes of Jupiter by NASA's Juno mission.

Jupiter’s complex transient auroras

Combined observations from three spacecraft show that Jupiter's brightest auroral features recorded to date are powered by both the volcanic moon Io and interaction with the solar wind. 

Juno mission to Jupiter delivers first science results

NASA's Juno mission is rewriting what scientists thought they knew about Jupiter specifically, and gas giants in general, according to a pair of Science papers released today. The Juno spacecraft has been in orbit around Jupiter since July 2016, passing within 3,000 miles of the equatorial cloudtops.

New 'styrofoam' planet provides tools in search for habitable planets

Researchers have discovered a new planet orbiting a star 320 light years from Earth that has the density of styrofoam. This 'puffy' exoplanet may hold opportunities for testing atmospheres that will be useful when assessing future planets for signs of life.
