Hubble Ultra Deep Field 2014 

Galaxies like colorful pieces of candy fill the Hubble Ultra Deep Field 2014. The dimmest galaxies are more than 10 billion times fainter than stars visible to the unaided eye and represent the Universe in the extreme past, a few 100 million years after the Big Bang. The image itself was made with the significant addition of ultraviolet data to the Hubble Ultra Deep Field, an update of Hubble’s famous most distant gaze toward the southern constellation of Fornax. It now covers the entire range of wavelengths available to Hubble’s cameras, from ultraviolet through visible to near-infrared. Ultraviolet data adds the crucial capability of studying star formation in the Hubble Ultra Deep Field galaxies between 5 and 10 billion light-years distant.

NGC 4258 (M106): Galactic Pyrotechnics On Display

A new composite of NGC 4258 features X-rays from Chandra (blue), radio waves from the VLA (purple), optical data from Hubble (yellow and blue), and infrared with Spitzer (red).

NGC 4258 is well known to astronomers for having “anomalous” arms that are not aligned with the plane of the galaxy, but rather intersect with it.

Researchers are trying to understand how the giant black hole in the center of NGC 4258 is affecting the rest of the galaxy.

NGC 4258, also known as Messier 106, is located about 23 million light years from Earth.

Let’s face it, the night sky does have some duds. Here’s a helpful guide to what you should avoid.

Today’s peek into the archives shows the arrival of the Willamette Meteorite to the Museum in 1906. 

Weighing 15.5 tons, this iron meteorite is the largest ever found in the United States and the sixth-largest in the world. The smooth surface melted during its blazing entry into the atmosphere, while the pits formed on the Earth’s surface.

The Willamette Meteorite was originally located within the Upper Willamette Valley of Oregon. It was revered as a spiritual being that has healed and empowered the people of the valley by the Clackamas Indians who occupied the region.
