This graphic shows how Hubble probed the light from the quasar PDS 456 to analyze the Fermi Bubbles. The quasar's light passed through one of the bubbles; imprinted on that light is information about the outflow's speed, composition, and eventually mass. Image credit: NASA / ESA / A. Field, STScI.

Eta Carinae's great eruption in the 1840s created the billowing Homunculus Nebula, imaged here by Hubble. Now about a light-year long, the expanding cloud contains enough material to make at least 10 copies of our Sun. Astronomers cannot yet explain what caused this eruption.

This image shows the Eagle Nebula’s Pillars of Creation as seen in visible light, capturing the multi-colored glow of gas clouds, wispy tendrils of dark cosmic dust, and the rust-colored elephants’ trunks of the nebula’s famous pillars. The dust and gas in the pillars is seared by the intense radiation from young stars and eroded by strong winds from massive nearby stars. Image credit: NASA / ESA / Hubble / Hubble Heritage Team.

X-rays stream off the Sun in this image. The NuSTAR data, seen in green and blue, reveal solar high-energy emission (green shows energies between 2 and 3 kiloelectron volts, and blue shows energies between 3 and 5 kiloelectron volts). The high-energy X-rays come from gas heated to above 3 million degrees. The red channel represents UV light captured by SDO at wavelengths of 171 angstroms, and shows the presence of lower-temperature material in the solar atmosphere at 1 million degrees. This image shows that some of the hotter emission tracked by NuSTAR is coming from different locations in the active regions and the coronal loops than the cooler emission shown in the SDO image.
