Galaxy star birth regulated by black-hole fountain

more »
Astronomers have uncovered a unique process for how the universe's largest elliptical galaxies continue making stars long after their peak years of star birth. Hubble Space Telescope's exquisite high resolution and ultraviolet-light sensitivity allowed the astronomers to see brilliant knots of hot, blue stars forming along the jets of active black holes found in the centers of giant elliptical galaxies.

NASA's Hubble Finds Evidence of Galaxy Star Birth Regulated by Black-Hole Fountain


Get larger image formats

Astronomers have long wondered how the universe's largest elliptical galaxies continue making stars long after their peak years of star birth. By combining data from NASA's Hubble Space Telescope with observations from a suite of ground-based and space telescopes, two independent teams have uncovered a unique process to explain how this star birth continues. The teams found that that the galaxy's central black hole, jets, and newborn stars are all parts of a self-regulating cycle. In that cycle, jets shooting out of the galaxy's center heat a halo of surrounding gas, controlling the rate at which it cools and falls into the galaxy. The astronomers used Hubble's high resolution and ultraviolet vision to resolve brilliant knots of hot, blue stars forming along the jets from active black holes in the centers of these giant galaxies.

We had no idea! An appreciation of science’s discoveries

Science Focus

original post »

The recent visit to Pluto by New Horizons has clearly captured a lot of people's attention. It's the first time in many years since we've seen an entirely new world, complete with geology and moons. For anyone younger than 25, it's not happened in their lifetime at all.

For me, however, it's a bit like coming full circle. I hadn't quite entered my teens when the Voyagers flew past Jupiter, and I recall it as being the point where I first really started paying attention to science. The Voyagers revealed the staggering violence of the planet's clouds and found that the planet-sized moons were alive with activity. The Solar System never quite looked the same again and, in a lot of ways, the whole Universe didn't. The Voyagers drove home in a big way how we could not only found out new things, but we could often manage to make sense out of them.

New Horizons got me thinking about all the different ways science has changed what we know about the world in the 35 or so years between the Voyagers reaching Jupiter and the present. So, I put together a completely arbitrary list of some of the discoveries that have happened in the intervening years.

Carina Nebula in Argo Navis constellation Classic Round Sticker

Here's a great sheet of stickers featuring a beautiful image from deep space


tagged with: stars, galaxies, astronomy, envelope sealers, carina nebula, argos navis constellation, carina the keel, star formation, carnebngcttst, outer space photography, gas clouds, ngc 3372

Galaxies, Stars and Nebulae series Hubble's view of the Carina Nebula shows star birth in a new level of detail. The fantasy-like landscape of the nebula is sculpted by the action of outflowing winds and scorching ultraviolet radiation from the monster stars that inhabit this inferno. In the process, these stars are shredding the surrounding material that is the last vestige of the giant cloud from which the stars were born. The immense nebula is an estimated 7,500 light-years away in the southern constellation Carina the Keel (of the old southern constellation Argo Navis, the ship of Jason and the Argonauts, from Greek mythology).
The original image is a mosaic of the Carina Nebula assembled from 48 frames taken with Hubble Space Telescope's Advanced Camera for Surveys. The Hubble images were taken in the light of ionized hydrogen. Colour information was added with data taken at the Cerro Tololo Inter-American Observatory in Chile. Red corresponds to sulfur, green to hydrogen, and blue to oxygen emission.

Stereo Pluto

more »
These two detailed, true color images of Pluto were captured during the historic New Horizons flyby last month. With slightly different perspectives on the now recognizeable surface features they are presented in this first high quality stereo pair intended for viewing by denizens of planet Earth. The left hand image (left eye) is a mosaic recorded when the spacecraft was about 450,000 kilometers from Pluto. The right single image was acquired earlier, a last full look before the spacecraft's closest approach. Despite a difference in resolution, the pair combine for a stunning 3D perception of the distant, underworldly terrain.
