This illustration uses data obtained by NASA’s Juno mission to depict high-altitude electrical storms on Jupiter. Juno’s sensitive Stellar Reference Unit camera detected unusual lightning flashes on Jupiter’s dark side during the spacecraft’s close flybys of the planet.

Astronomers have found another strange exoplanet in a distant solar system. This one’s an oddball because its size is intermediate between Earth and Neptune, yet it’s 50% more massive than Neptune. Astronomers have found what they call “puff planets” in other Solar Systems. Those are planets that are a few […]

Taking advantage of a total lunar eclipse in January 2019, astronomers using NASA’s Hubble Space Telescope have detected ozone in Earth’s atmosphere. This method serves as a proxy for how they will observe Earth-like planets transiting in front of other stars in search of life. Our planet’s perfect alignment with […]

Illustration shows how the star’s motion around the center of mass between it and the planet causes a “wobble” in its motion through space. The VLBA’s ability to detect this minuscule effect revealed the presence of the planet. Credit: Bill Saxton, NRAO/AUI/NSF Using the supersharp radio “vision” of the National […]

ANIMATION A study led by researchers at the Instituto de Astrofísica de Canarias (IAC), making comparison between the discs of several pairs of spiral galaxies, active and non-active, concludes that in the discs of the former the rotational motion of the stars is of greater importance. This study, just accepted […]

Artist’s concept of Lucy Mission. Credit: SwRI Last week marked the completion of a major milestone on the path to spacecraft assembly, test, and launch operations for NASA’s Lucy mission. The Systems Integration Review ensured segments, components, and subsystems, scientific instrumentation, electrical and communication systems, and navigation systems are on schedule to […]

Molten lava in crucible placed under experimental setup. Setup includes a spectrometer (right) which measures the light from the lava at different wavelengths. Credit: Tajana Schneiderman By making their own lava and cooled glass, scientists find these materials likely aren’t responsible for the unexpected glow of some exoplanets. Arguably some […]

The moon Io orbits Jupiter in this image from NASA’s Cassini spacecraft. Jupiter and Io appear deceptively close in this image, when in fact the moon is orbiting 217,000 miles from the gas giant planet.
