Polish astronomers just discovered two new planets in our galaxy. That’s cool news on its own, but these planets are different from most. Unlike almost all known planets, New Scientist reports, these two planets don’t orbit a star.
Instead, they drift aimlessly through the cold, dead void of space — and presumably spend their time writing angsty poetry.
Astronaut Serena Auñón-Chancellor planted ‘Red Russian’ kale and ‘Dragoon’ lettuce in a special garden last month and if all goes well, they will be ready to enjoy for Thanksgiving! Dig in: https://go.nasa.gov/2F45vvj
There is evidence that star clusters start out close, as giant collisions between massive molecular clouds, but then the stellar siblings scatter throughout our galaxy. Evidence was collected using SOFIA Stratospheric Observatory for Infrared Astronomy —which is The Boeing Company’s jetliner modified to carry a 106-inch diameter telescope.
Whoa.
NASA just released this new close-up photo of the swirling clouds found on Jupiter. It was captured by the Juno spacecraft on October 29th, 2018, during its 16th close flyby of the gas giant.
The clouds in the photo were seen in Jupiter’s North-North Temperate Belt (NNTB), one of the distinct cloud bands.

A small device that contains human cells in a 3D matrix represents a giant leap in the ability of scientists to test how those cells respond to stresses, drugs and genetic changes. About the size of a thumb drive, the devices are known as tissue chips or organs on chips.
A series of investigations to test tissue chips in microgravity aboard the International Space Station is planned through a collaboration between the National Center for Advancing Translational Sciences (NCATS) at the National Institutes for Health (NIH) and the Center for the Advancement of Science in Space (CASIS) in partnership with NASA. The Tissue Chips in Space initiative seeks to better understand the role of microgravity on human health and disease and to translate that understanding to improved human health on Earth.

11.08.18 JOVIAN CLOSE ENCOUNTER A multitude of magnificent, swirling clouds in Jupiter’s dynamic North North Temperate Belt is captured in this image from NASA’s Juno spacecraft. Appearing in the scene are several bright-white “pop-up” clouds as well as an anticyclonic storm, known as a white oval. This color-enhanced image was taken at 1:58 p.m. PDT on Oct. 29, 2018 (4:58 p.m. EDT) as the spacecraft performed its 16th close flyby of Jupiter. At the time, Juno was about 4,400 miles (7,000 kilometers) from the planet’s cloud tops, at a latitude of approximately 40 degrees north. Citizen scientists Gerald Eichstädt and Seán Doran created this image using data from the spacecraft’s JunoCam imager. JunoCam’s raw images are available for the public to peruse and to process into image products at: https://www.missionjuno.swri.edu/news/jovian_close_encounter.

Amid the high speed cosmic rays raining down on us from the depths of space are a handful of antimatter particles called positrons.
Astronomers think that Earth is showered by these ‘anti-electrons’ because of pulsars, but there’s a weird catch – there are more of these particles coming at us than there should be. And now, thanks to a new study, we might finally get some answers.
Cosmic rays are incredibly fast particles, since they’re being shot down from space at high energies. Positrons make up a small percent of these super speedy particles, but nobody is entirely sure where or how they’re made.
We hear a lot about Mars, Jupiter, and Saturn, and that’s because we have extremely fancy hardware floating around and, in some cases, cruising on the surface of those planets. The planets that lie further away from the Sun don’t get nearly as much attention, but they may soon, as NASA is currently spitballing some missions that will give us a better look at Uranus than we’ve ever gotten.
