Wonderful

Nearly a millennium ago sky-watchers recorded a new star so bright it was visible in daylight for weeks, and Hubble has now traced how far its remnant, the Crab Nebula, has expanded since — a thousand-year-old explosion still visibly unfolding

In July 1054, court astronomers in China recorded a new "guest star" near Tianguan, the star we now call Zeta Tauri.

A mystery in the heavens

Hubble Finds Unidentified Object in Space

From Sky & Telescope via Gizmodo by way of Slashdot, with the following blurb submitted by ScuttleMonkey:

Gizmodo is reporting that the Hubble space telescope has found a new unidentified object in the middle of nowhere. Some are even suggesting that this could be a new class of object. Of course, without actually understanding more about it, the speculation seems a bit wild.

The object also appeared out of nowhere. It just wasn't there before. In fact, they don't even know where it is exactly located because it didn't behave like anything they know. Apparently, it can't be closer than 130 light-years but it can be as far as 11 billion light-years away. It's not in any known galaxy either. And they have ruled out a supernova too. It's something that they have never encountered before. In other words: they don't have a single clue about where or what the heck this thing is.

Also from the Gizmodo story:

Apparently, a scientist at the LHC declared that the object is similar to the flash that an Imperial Star Destroyer does when reaching Warp 10, confusing Star Wars and Star Trek.

:)

The object brightened over a 100-day period, then faded over the same period of time. Strange, no?
