Segue 1 is a billion times fainter than our galaxy. Receive news, sky-event information, observing tips, and 4.5 out of 5 stars 975. Arecibo radio telescope finally collapses following cable failures, 7 naked-eye supernovae throughout human history. There are objects out there that are so faint they're hard to study well, and so faint we didn't even know they existed until pretty recently. The amount of iron in globular cluster stars is about the same from star to star, but very different in galaxies. But the more things you find and classify, the more likely it is you'll find things that don't want to fit into one box or another. Yeah, you don't. Credit: The location of the teeny tiny galaxy Segue-1, which is pretty much too faint to even see in this image, despite being right in the center. We present Keck/DEIMOS spectroscopy of Segue 1, an ultra-low-luminosity (M V = -1.5 +0.6-0.8) Milky Way satellite companion.While the combined size and luminosity of Segue 1 are consistent with either a globular cluster or a dwarf galaxy, we present spectroscopic evidence that this object is a dark matter-dominated dwarf galaxy. The location of the teeny tiny galaxy Segue-1, which is pretty much too faint to even see in this image, despite being right in the center. Segue-1's stars had a significant spread in iron abundances. Segue 1 is a dwarf spheroidal galaxy or globular cluster situated in the Leo constellation and discovered in 2006 by Sloan Digital Sky Survey.

Observations of the Segue 1 dSph were performed between January 2010 and May 2011, at a mean zenith angle of 20 . That's a good question. Measuring their motions means waiting long enough for that motion to make itself clear, and that takes time too, so we're really only just starting to get a grip on these wee beasties. It's a galaxy! The simulations don't really say for sure if Segue-1 was a companion to some other galaxy the Milky Way ate or if it formed out there all alone. on Twitter, Share Where did this tiny ghostly galaxy Segue-1 come from? And yet its light is off-the-chart faint, coming from a paltry number of stars. It is classified as a dwarf spheroidal galaxy (dSph) meaning that it has an approximately round shape with a half-light radius of about 34 pc. Doing so, we find a ratio of visible-to-dark-matter of about 1:8 in galaxies within our neighborhood. A team of astronomers looked at data measuring the positions of the stars over a ten-year baseline to very carefully measure their motion. That means there's a mystery left to solve, and we'll have to be clever to solve it. That's it. $30.99 - $35.99 #37.

SEGUE. Find new and preloved Segue items at up to 70% off retail prices. But not everything. Unlike most other galaxies, Segue 1 is not six or eight times more massive than it appears, but, to repeat, a thousand times more massive. They run through some subtle arguments to try to figure this out, and while the evidence is circumstantial, they argue that it's more likely Segue-1 formed as is and has been orbiting us for more than 8 billion years.
