NPR: Hubble Captures Time-Lapse Videos Of Stars Being Born

(Movies of jets from young stars at HubbleSite: here)

If you’re like me and maybe a little confused as to what you’re looking at, here’s some more detail (Yes, even Joe has to look stuff up sometimes): 

As a star is formed from collapsing dust, ever increasing its density and energy, it begins to form a disk of dust and gas pulled in and rotated by its growing gravity. Perpendicular to this disk, like the tip of a spinning top, some gas is ejected away from the growing star in a high-energy jet. As this collides with interstellar gas, it gives off radiation, which we can observe with telescopes like Hubble.

To see the jets, we have to shift into the infrared and other spectra, as the radiation is outside normal human vision. These movies represent the first time we’ve seen the dynamics of the jets as opposed to still images. More info on protostellar jets here, you star-freaks.

Scientists Find Thousands Of Previously Undiscovered Species Cowering In Amazon Rainforest

As usual, The Onion’s best comedy is that which is just barely beyond truth. If you don’t laugh, you just may cry.

“Our expedition has shown that the Amazon Rainforest is simply teeming with a multitude of creatures never before glimpsed in this region,” said lead researcher professor Courtland Gere, who personally observed a rare form of spider monkey as it huddled, shaking, inside the stump of a freshly felled tree. “Just mere minutes after our vehicles entered the forest, our team was lucky enough to hear the grief-stricken whimpers of a fascinating, previously unknown species of striped jaguar locked in the fetal position under a pile of leaves.”
