Indian astronomers measure temperature of the early universe

London, May 16 : A team led by Raghunathan Srianand of the Inter-University Centre for Astronomy and Astrophysics in Pune, India, has measured what the temperature of the Universe was 11 billion years ago, when it was just a fifth its current age.

Astronomers Take The Temperature Of Distant Universe

Astronomers have made use of ESO's Very Large Telescope to detect for the first time in the ultraviolet the carbon monoxide molecule in a galaxy located almost 11 billion light-years away, a feat that had remained elusive for 25 years. This detection allows them to obtain the most precise measurement of the cosmic temperature at such a remote epoch.

Tapping Early Universe For Secrets Of Fundamental Physics

The future of fundamental physics research lies in observing the early universe and developing models that explain the new data obtained. The availability of much higher resolution data from closer to the start of the universe is creating the potential for further significant theoretical breakthroughs and progress resolving some of the most difficult and intractable questions in physics. But this requires much more interaction between astronomical theory and observation, and in particular the development of a new breed of astronomer who understands both.

Dust dimming our universe

Astronomers from UK universities, working with colleagues from Germany and Australia, have calculated that the universe is actually twice as bright as previously thought. In the May 10th Astrophysical Journal Letters, the astronomers describe how dust is obscuring approximately half of the light that the universe is currently generating.

Odd objects between Uranus and Neptune may shed light on early solar system

London, June 5 : Astronomers searching for distant supernovae to probe dark energy in the early universe have stumbled upon two relatively nearby objects between Uranus and Neptune that may shed light on the early solar system.

This Week's "Where in the Universe?" Challenge

Here's your image for this week's "Where in the Universe?" challenge. Take a look at the image and before proceeding to the end of this post, make your guess as to what location in the universe is represented here. It could be anywhere — nothing is off limits for this challenge! Near or distant, far and wide, Universe Today spares no expense when it comes to searching for unique and unusual images to test your visual knowledge of our universe! Give yourself an extra point for guessing (or knowing) the feature shown here, and another point for naming the spacecraft that took this image. Just a couple more ticks on the timer here before revealing the awesome power of this week's image….

There's A lot of Dust Out There in the Universe

The whole point of putting telescopes in orbit is to avoid distortions caused by our murky atmosphere. But now astronomers say they have calculated only half the light of our universe reaches telescopes – even those in orbit – because of the amount of dust that permeates the universe. In essence, they say, the universe is twice as bright as previously thought. The lead author of a new paper detailing this discovery, Dr. Simon Driver from the University of St Andrews said, “For nearly two decades we’ve argued about whether the light that we see from distant galaxies tells the whole story or not. It doesn’t; in fact only half the energy produced by stars actually reaches our telescopes directly, the rest is blocked by dust grains.”

Doughnut-Shaped Universe Back In the Race

SpaceAdmiral writes "The once-popular idea that the universe could be small and finite is making a comeback. Many researchers thought that a 'wraparound' universe would mean that distant objects would be seen multiple times in the sky, but new research suggests that a '3-torus' (or 'doughnut universe'), as well as other shapes, could fit our actual observations, particularly the WMAP data."

Biomarkers Of Early-stage Pancreatic Cancer In Mice And Man Identified

A multicenter team of researchers has identified a panel of proteins linked to early development of pancreatic cancer in mice that applies also to early stages of the disease in humans -- a breakthrough that brings scientists a significant step closer to developing a blood test to detect the disease early, when cure rates are highest.

Study Hints At Time Before Big Bang

canadian_right informs us that scientists from Caltech have found hints of a time before the Big Bang while studying the cosmic microwave background. Not only does the study hint at something pre-existing our universe, the researchers also postulate that everything we see was created as a bubble pinched off from a previously existing universe. This conjecture turns out to shed light on the mystery of the arrow of time. Quoting the BBC's account: "Their model suggests that new universes could be created spontaneously from apparently empty space. From inside the parent universe, the event would be surprisingly unspectacular. Describing the team's work at a meeting of the American Astronomical Society (AAS) in St Louis, Missouri, co-author Professor Sean Carroll explained that 'a universe could form inside this room and we'd never know.

GLAST blasts off in search of gamma rays

The GLAST gamma-ray telescope was launched into space at 12.05 p.m. local time from Cape Canaveral in Florida today. The instrument is due to orbit some 360 km above the Earth’s surface where it will begin its survey of gamma rays from throughout the universe. Physicists involved in the project hope that GLAST (the Gamma-ray Large Area Space Telescope) will help them study some of the most violent events in the universe, provide a new window into the early universe and even shed light on the origins of dark matter.
