Astronomers use vanishing neutron star to measure space-time warp

more »

In an interstellar race against time, astronomers have measured the space-time warp in the gravity of a binary star and determined the mass of a neutron star—just before it vanished from view.

'Assassin' targets supernovae in our neighborhood of the universe

more »

While many astronomical collaborations use powerful telescopes to target individual objects in the distant universe, a new project at The Ohio State University is doing something radically different: using small telescopes to study a growing portion of the nearby universe all at once.

No signals from newest Kepler planet

more »

A newly discovered planet has been observed with the Allen Telescope Array in a search for radio signals that would betray technically sophisticated inhabitants, but no transmissions have been detected.

Defying the Achilles heel of 'wonder material' graphene: Resilience to extreme conditions

more »

A resilience to extreme conditions by the most transparent, lightweight and flexible material for conducting electricity could help revolutionize the electronic industry, according to a new study. Researchers have discovered that a material adapted from the 'wonder material' graphene can withstand prolonged exposure to both high temperature and humidity.

Saturn Solar Eclipse Posters

Here's a great poster featuring a beautiful image from deep space


tagged with: space, astronomy, saturn, stars, planets, earth, cassini, sun, exploration, rings, moons

You may think that this is a fake image, but it is actually a real photo taken from the Cassini space craft of Saturn eclipsing the Sun. The rings glow brightly as the light filters through them and the reflect that light all the way around to the back of the planet creating a surreal effect. A special surprise in the photo is that, just to the left of the rings, that bright blue dot is Earth, where you're sitting right now. This is truly a fascinating and beautiful image.

Researchers succeed in measuring the temperature at the heart of stars

more »

Researchers have succeeded, for the first time, in measuring the temperature at the heart of certain stars, as well as dating them. In 1926, astrophysicist Sir Arthur Eddington wrote in his work The internal constitution of the stars: “At first sight it would seem that the deep interior of the Sun and stars is less accessible to scientific investigation than any other region of the universe. What appliance can pierce through the outer layers of a star and test the conditions within?” Nearly 90 years later, this question has now gained an answer, thanks to the work of a team of six astrophysicists who have managed to measure the temperature at the heart of specific stars and to estimate their age.

What do we expect of a space program? (Synopsis)

more »


“This Administration has never really faced up to where we are going in space… As a result, NASA is both drifting and lobbying for bigger things — without being able to focus realistically on what it should be doing.”

-
White House staff assistant Clay Thomas Whitehead, February 1971



What should we be doing with respect to our space program? At its peak — the mid-1960s — the US government spent somewhere around 20% of its non-military discretionary spending on NASA and space science/exploration. Today?

That number is down to 3%, the lowest it’s ever been. As far as our priorities as a nation go, is this right?


In an enraging talk at the annual American Astronomical Society meeting, John M. Logsdon argued that we should be happy, as a community, that we still get as much funding as we do, despite all the we could (and won’t) accomplish if our funding would increase.

Needless to say, I think we need to rethink this defeatist point of view. What’s your opinion?

Mini-Movie Monday: Genesis Episode 4: Atoms (Synopsis)

more »


“A physicist is just an atom’s way of looking at itself.” -Niels Bohr



There’s a wonderful story that the Universe tells us about itself: the story of where everything in it came from, and how it came to be this way. From the perspective of a human being, there’s possibly no component of that as important to our existence as the humblest of all building blocks: the atoms.

Yet when the Universe first cooled from the Big Bang, over 99.999999% of what existed was nothing more than hydrogen and helium. So where did the atoms that make us up come from?


This sounds like a job for our Genesis series, so check out episode 4: Atoms!

Why do galaxies have black eyes? (Synopsis)

more »


“With an eye made quiet by the power of harmony, and the deep power of joy, we see into the life of things.” -William Wordsworth



You’ve seen the amazing photos of spiral galaxies, with the vast, sweeping arms, the massive, central bulges and the great underdense regions in between the arms. As you move farther and farther towards the outskirts, the stellar density drops away to practically nothing.

But if you see these galaxies at an angle, rather than face-on, you’re likely to notice that there’s not only the presence of dust, but that one “side” of the galaxy almost always appears “dustier” than the other!

Super-insulated clothing could eliminate need for indoor heating

more »

(Phys.org)—By wearing clothes that have been dip-coated in a silver nanowire (AgNW) solution that is highly radiation-insulating, a person may stay so warm in the winter that they can greatly reduce or even eliminate their need for heating their home. Considering that 47% of global energy is spent on indoor heating, and 42% of that specifically for residential heating, such highly insulating clothing could potentially have huge cost savings.

Carina Nebula in Argo Navis constellation Sticker

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


tagged with: stars, galaxies, astronomy, peel off, carina nebula, argos navis constellation, carina the keel, star formation, gas clouds, carnebngcttst, 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.

Stars and Dust in Corona Australis

more »
Cosmic dust clouds and young, energetic stars inhabit this telescopic vista, less than 500 light-years away toward the northern boundary of Corona Australis, the Southern Crown. The dust clouds effectively block light from more distant background stars in the Milky Way. But the striking complex of reflection nebulae cataloged as NGC 6726, 6727, and IC 4812 produce a characteristic blue color as light from the region's young hot stars is reflected by the cosmic dust. The dust also obscures from view stars still in the process of formation. At the left, smaller yellowish nebula NGC 6729 bends around young variable star R Coronae Australis. Just below it, glowing arcs and loops shocked by outflows from embedded newborn stars are identified as Herbig-Haro objects. On the sky this field of view spans about 1 degree. That corresponds to almost 9 light-years at the estimated distance of the nearby star forming region.
