hubble’s panorama of the carina nebula, some 7500 light years away from earth, and about fifty light years in length here. stars old and new illuminate clouds of cosmic dust and gas, like the clumping hydrogen from which they were born. 

the top star seen at the bisection of the first two panels, part of the eta carinae binary star system (most stars are in binary systems), is estimated  to be more than a hundred times the mass of the sun - large enough to go supernoava in about a million years. 

it also produces four million times as much light as the sun, and was once the second brightest star in the night sky. but surrounding dust and gas has dimmed our view of the star, though it’s still visible in the night sky to all but those in the most light polluted cities.

the fifth panel shows ‘the mystic mountain,’ where nascent stars in the dust cloud are spewing hot ionized gas and dust at 850,000 miles an hour. eventually, the ultraviolet radiation from these stars will blow away the dust, leaving visible the stars, like the cluster seen at the top of the panel, which were formed only half a million years ago.

AIR!

Earth’s atmosphere recently crossed 400 ppm CO2 for the first time in millions of years and probably will not go back below that amount during any of our lifetimes. (http://tinyurl.com/bus4xpt). But did you know there’s something else changing in the atmosphere to go along with that CO2 rise?

It’s pictured in this graph. This gas is going down, decreasing in the atmosphere as CO2 goes up. That gas? Oxygen. Oxygen in the atmosphere is decreasing.

Be honest…did you just stop and take a deep breath? It really is kinda creepy to realize that the gas everyone is taught as a kid they need to survive is going down in the atmosphere.

Anyway, why is oxygen going down? The same reason that carbon is going up; burning of fossil fuels.

I saw this a long time ago and finally got it to convert to GIF format on tumblr. It shows how it’s the Earth that’s moving, space is standing still. I love this perspective. 

Chandra X-Ray Observatory, We Appreciate You

On July 23, 1999, the Space Shuttle Columbia blasted off from the Kennedy Space Center carrying the Chandra X-ray Observatory. In the two decades that have passed, Chandra’s powerful and unique X-ray eyes have contributed to a revolution in our understanding of the cosmos.

Since its launch 20 years ago, Chandra’s unrivaled X-ray vision has changed the way we see the universe.

Chandra has captured galaxy clusters – the largest gravitationally bound objects in the universe – in the process of merging.

Chandra has shown us the powerful wind and shock fronts that rumble through star-forming systems.

And a star school, so to speak – home to thousands of the Milky Way’s biggest and brightest.

Carl Sagan said, “We are made of star-stuff.“ It’s true. Most of the elements necessary for life are forged inside stars and blasted into interstellar space by supernovas. Chandra has tracked them.

Thank you Chandra X-Ray! To more adventures with you!

Check out Chandra’s 20th anniversary page to see how they are celebrating.

It’s Surprisingly Easy To Brew Something Like RNA In A Puddle 

One of the biggest mysteries in science is how you could get life in a place where it doesn’t already exist. Scientists have found some clues, though.

The latest is that Georgia Tech chemist Nicholas Hud was able to create something that looks a lot like RNA — a relative of DNA — using ingredients that would have been common on Earth when it was 4 billion years younger.

The study used two common chemicals left alone in what amounts to a mud puddle. The chemicals synced up and started forming that twisting ladder shape we think of when we picture DNA.

Scientists say this looks like a decent candidate for how simple organisms may have gotten started on Earth, and it wasn’t even all that hard.

Earlier studies have shown you can get some of the building blocks of life in the right situation, like extreme heat or lightning strikes. Some have even been found on asteroids.

The Georgia Tech study shows you don’t even need that much excitement. Swirling puddles could potentially have done the job.

Three galaxies at once

Rising majestically above the telescopes of ESO’s La Silla Observatory in Chile we see the Milky Way accompanied by its two dwarf neighbour galaxies, the Large and Small Magellanic Clouds.
