Galaxy Found With Almost No Dark Matter

This could be a proof of Dark Matter.

Galaxies litter the cosmos in a picture of the deep universe taken by the Hubble Space Telescope. A closer look at a galaxy 65 million light-years away suggests that it is missing a fundamental part of the usual galactic recipe: the mysterious substance known as dark matter.

An unusual galaxy far, far away is stumping astronomers not because of what’s there, but because of what’s missing.

About 65 million light-years away, the galaxy called NGC1052-DF2 is dim and diffuse, coming in at about one two-hundredths the mass of our Milky Way.

Normally, not all of a galaxy’s mass is visible. In addition to a mix of ordinary matter—like stars and planets and manatees—galaxies are expected to contain dark matter, an invisible substance that makes up most of the mass in the universe. Although we can’t directly observe it, we know dark matter is there because we can see how its gravity affects ordinary matter.

Based on the ratio in other galaxies, an isolated galaxy like NGC1052-DF2 should have about a hundred times more dark matter than ordinary matter. But this one appears to have … almost none, scientists report today in Nature.

Celestial Pick – Pterosaurs

2-Quetzalcoatlus-ModelPterosaurs swoop in to become this week’s best geek bet in Cleveland. The Cleveland Museum of Natural History’s new exhibit, Pterosaurs: Flight in the Age of Dinosaurs has opened. A trip down to enjoy this traveling exhibit from the American Museum of Natural History, New York offers flying reptiles of all sizes:

They flew with their fingers. They walked on their wings. Some were gigantic, while others could fit in the palm of your hand. Millions of years ago, the skies were ruled by pterosaurs — the first vertebrates to achieve flight.

Not dinosaurs, birds or bats, pterosaurs were flying reptiles that lived in the world of dinosaurs 220 to 66 million years ago. This exhibit from the American Museum of Natural History, New York, showcases rare fossils, life-size models and activities that bring pterosaurs to life.

While you are there, check out a planetarium show or enjoy the animals as Spring breaks out and warms the ground. The Ralph Perkins II Wildlife Center & Woods Garden offers a delightful collection of active animals this time of year.

otterThe Cleveland Museum of Natural History is located in Cleveland’s museum circle at 1 Wade Oval Drive Cleveland, Ohio, 44106. Their hours are 10 am to 5 pm Monday, Tuesday and Thursday through Saturday, 10 am to 10 pm Wednesday, and noon to 5 pm Sunday. Admission rates vary by age, running from $12 to $15, except Wednesday evenings. Drop by after 5 pm . Wednesday for an $8 admission! Parking in the connected garage runs $10 – $16.

Looking for a great Pterosaur to take with you? May we suggest a plush pterosaur sized tiny, small (13″), medium (15″) or large (22″)? They range in wingspans from just two to a massive 22 inches. The medium, 15-inch, is on sale for just $12.99. Trust us, the real thing was far less cuddly.

In that spirit Cleveland, we encourage you to start planning your mayhem now. This will be the last year you can count on Big Fun in Coventry for your gag gift needs. Make the most of it.
