Hubble Sights Galaxy Stuck in the Middle



This pretty, cloud-like object may not look much like a galaxy but it is in fact something known as a lenticular galaxy.

Ganymede: A Moon Like No Other



Far across the solar system, where Earth appears merely as a pale blue dot, NASA’s Galileo spacecraft spent eight years orbiting Jupiter. Newly resurrected data from Galileo's first flyby of Jupiter's moon Ganymede is yielding new insights.

Hubble Sees the Force Awakening in a Newborn Star



Just in time for the release of the movie “Star Wars Episode VII: The Force Awakens,” NASA’s Hubble Space Telescope has photographed what looks like a cosmic, double-bladed lightsaber. In the center of the image, partially obscured by a dark, Jedi-like cloak of dust, a newborn star shoots twin jets out into space as a sort of birth announcement to the universe. “Science fiction has been an inspiration to generations of scientists and engineers, and the film series Star Wars is no exception,” said John Grunsfeld, astronaut and associate administrator for the NASA Science Mission directorate. “There is no stronger case for the motivational power of real science than the discoveries that come from the Hubble Space Telescope as it unravels the mysteries of the universe

This celestial lightsaber does not lie in a galaxy far, far away, but rather inside our home galaxy, the Milky Way. It’s inside a turbulent birthing ground for new stars known as the Orion B molecular cloud complex, located 1,350 light-years away. When stars form within giant clouds of cool molecular hydrogen, some of the surrounding material collapses under gravity to form a rotating, flattened disk encircling the newborn star. Though planets will later congeal in the disk, at this early stage the protostar is feeding on the disk with a Jabba-like appetite. Gas from the disk rains down onto the protostar and engorges it. Superheated material spills away and is shot outward from the star in opposite directions along an uncluttered escape route — the star’s rotation axis. Shock fronts develop along the jets and heat the surrounding gas to thousands of degrees Fahrenheit. The jets collide with the surrounding gas and dust and clear vast spaces, like a stream of water plowing into a hill of sand.

The shock fronts form tangled, knotted clumps of nebulosity and are collectively known as Herbig-Haro (HH) objects. The prominent HH object shown in this image is HH 24. Just to the right of the cloaked star, a couple of bright points are young stars peeking through and showing off their own faint lightsabers — including one that has bored a tunnel through the cloud towards the upper-right side of the picture. Overall, just a handful of HH jets have been spotted in this region in visible light, and about the same number in the infrared. Hubble’s observations for this image were performed in infrared light, which enabled the telescope to peer through the gas and dust cocooning the newly forming stars and capture a clear view of the HH objects.

These young stellar jets are ideal targets for NASA’s upcoming James Webb Space Telescope, which will have even greater infrared wavelength vision to see deeper into the dust surrounding newly forming stars. The Hubble Space Telescope is a project of international cooperation between NASA and the European Space Agency.

NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope. The Space Telescope Science Institute (STScI) in Baltimore, Maryland, conducts Hubble science operations. STScI is operated for NASA by the Association of Universities for Research in Astronomy, in Washington, D.C.

I think this means I am also a "Protostar" in the Orion B Molecular Cloud Complex. Because I too have a Jabba-Like appetite. Grabbing my light saber right now.

Gah...I HATE that a fricken SPACE FORCE FOR WAR is dominating even my most science based news feeds the last few days.

Buncha damned war mongers trying to claim space as their own and silo'ing countries. The human race doesn't deserve space yet and we are our own limiting factor.

That is all.

When do we leave?

The lone active region visible on the sun put on a fine display with its tangled magnetic field lines swaying and twisting above it (Apr. 24-26, 2018) when viewed in a wavelength of extreme ultraviolet light. The charged particles spinning along these field lines illuminate them. The region did not erupt with any significant solar storms, although it still might.

In case anyone wants to really check out all the photos that are taken in space you can visit:

Astronaut Photos


You can set parameters in the advanced search and get a list, picture, or other view of all the photos. Many are not yet cataloged and raw, so you see a ton of shots in the series that they usually only grab one or two from. Very cool.

Here is one I just did look at some taken this month, then displayed with a small picon.

Gravity’s Rainbow



Saturn’s rings display their subtle colors in this view captured on Aug. 22, 2009, by NASA’s Cassini spacecraft.

Uranus Moon - Titania



The terminator region of Titania, one of Uranus five large moons, was captured in this Voyager 2 image obtained in the early morning hours of Jan. 24, 1986.

On March 13, 2006 Cassini's narrow-angle camera captured this look at Saturn and its rings, seen here nearly edge on. The frame also features Mimas and tiny Janus (above the rings), and Tethys (below the rings). "Above" and "below" the rings is mostly a matter of perspective here.

All three moons and the rings orbit Saturn in roughly the same plane. The night side of Mimas is gently illuminated by "Saturnshine," sunlight reflected from the planet's cloud tops. Images taken using red, green and blue spectral filters were combined to create this natural color view, taken at a distance of approximately 1.7 million miles (2.7 million kilometers) from Saturn.

The Cassini spacecraft ended its mission on Sept. 15, 2017.

Fun fact: Even though no sovereign Nation recognizes human claim to "space real estate", Gregory W. Nemitz registered land on an asteroid that was full of Platinum. When NASA sent a probe there he sent NASA a $20 parking ticket

That was a pretty fun fact.
