Selfie Time with Astronaut Victor Glover

on Tue Nov 26 2024

Hey there, space enthusiasts! 🚀 Last Friday, November 8, 2024, something pretty awesome went down at NASA’s Kennedy Space Center in Florida.

This floating ring is the size of a galaxy. In fact, it is a galaxy — or at least part of one: the photogenic Sombrero Galaxy is one of the largest galaxies in the nearby Virgo Cluster of Galaxies. The dark band of dust that obscures the mid-section of the Sombrero Galaxy in visible light […]

Mini NASA Robot Takes a SWIM

on Mon Nov 25 2024

This robot prototype was built at NASA’s Jet Propulsion Laboratory in Southern California to demonstrate the feasibility of a mission concept called SWIM, short for Sensing With Independent Micro-swimmers. SWIM envisions a swarm of dozens of self-propelled, cellphone-size robots exploring the waters of icy moons like Jupiter’s Europa and Saturn’s Enceladus. via NASA https://ift.tt/b6iP8oG

One of the most identifiable nebulas in the sky, the Horsehead Nebula in Orion, is part of a large, dark, molecular cloud. Also known as Barnard 33, the unusual shape was first discovered on a photographic plate in the late 1800s. The red glow originates from hydrogen gas predominantly behind the nebula, ionized by the […]

What lies at the center of our galaxy? In Jules Verne’s science fiction classic, A Journey to the Center of the Earth, Professor Liedenbrock and his fellow explorers encounter many strange and exciting wonders. Astronomers already know of some of the bizarre objects that exist at our Galactic Center, including vast cosmic dust clouds, bright […]

Interplanetary Earth

on Sat Nov 23 2024

In an interplanetary first, on July 19, 2013 Earth was photographed on the same day from two other worlds of the Solar System, innermost planet Mercury and ringed gas giant Saturn. Pictured on the left, Earth is the pale blue dot just below the rings of Saturn, as captured by the robotic Cassini spacecraft then […]

Icelandic Cyclones

on Fri Nov 22 2024

A cyclone is a low-pressure area of winds that spiral inwards. Although tropical storms most often come to mind, these spiraling storms can also form at mid- and high latitudes. Two such cyclones formed in tandem south of Iceland in November 2006. via NASA https://ift.tt/QOLeXst

The Medusa Nebula

on Fri Nov 22 2024

Braided and serpentine filaments of glowing gas suggest this nebula’s popular name, The Medusa Nebula. Also known as Abell 21, this Medusa is an old planetary nebula some 1,500 light-years away in the constellation Gemini. Like its mythological namesake, the nebula is associated with a dramatic transformation. The planetary nebula phase represents a final stage […]

Ring Around Tabby’s Star

on Thu Nov 21 2024

This illustration depicts a hypothetical uneven ring of dust orbiting KIC 8462852, also known as Boyajian’s Star or Tabby’s Star. Astronomers have found the dimming of the star over long periods appears to be weaker at longer infrared wavelengths of light and stronger at shorter ultraviolet wavelengths. via NASA https://ift.tt/NuRifrB
