In 1970, on behalf of Nasa and with the help of Italian engineers, Kenya launched Uhuru#Swahili for"freedom##the world's first satellite dedicated to celestial X-ray astronomy, from a converted oil platform off its coast.

But for astronomers like Joe Liske, this is arguably the world's most interesting mountain right now,

In the past decade alone, astronomers have been discovering planets outside our solar system or exoplanets, with astonishing speed.

astronomers need incredibly sharp, high-resolution pictures. The bigger the mirror, the sharper the image a telescope can capture,

Mirror imagewhile astronomers wait for the E-ELT to be constructed other telescopes are busy scanning the skies for faraway worlds.

but gives astronomers headaches. NACO cancels out the turbulence, producing images as sharp as if snapped in space.

Sphere for the VLT and Gemini Planet Imager (GPI) for the Gemini Telescope in Chile"will blow NACO and Keck AO away#,according to Bruce Macintosh, an astronomer at Lawrence Livermore National Laboratory.

That's why astronomers put so much hope in the coming generation of optical giants. Besides the E-ELT, two other observatories have recently been given the go-ahead:

But now a team of astronomers led by Laura Kreidberg and Jacob Bean of the University of Chicago has detected clear evidence of clouds in the atmosphere of GJ 1214b from data collected with the Hubble space telescope.

This allowed the astronomers to rule out cloud-free atmospheres made of water vapor methane nitrogen carbon monoxide or carbon dioxide.

MKIDS are used in astronomy for taking measurements across the electromagnetic spectrum. In his lab at UC Santa barbara Mazin has adapted these detectors for the ultraviolet optical and near-IR parts of the spectrum.

MKIDS which operate at cryogenic temperatures (typically 0. 1 Kelvin) allow astronomers to determine the energy

This allows astronomers to see rapidly changing events a great advantage for many observations. MKIDS have inherent frequency domain multiplexing capabilities

#Nearby star is almost as old as the Universe Astronomers have discovered a Methuselah of stars#a denizen of the Solar system's neighbourhood that is at least 13.2 billion years old and formed shortly after the Big bang."

says Howard Bond, an astronomer at Pennsylvania State university in University Park, who announced the finding on 10 january at a meeting of the American Astronomical Society in Long beach, California1.

and has been studied by astronomers for more than a century. Researchers have known long that the object consists almost entirely of hydrogen

The astronomers also measured the brightness of the star as it appears in the sky,

The discovery places constraints on early star formation, says Volker Bromm, an astronomer at the University of Texas at Austin.

which limits astronomers ability to detect them with Kepler. But the star Kepler 37 is bright and relatively free of disturbances, such as starspots,

says Greg Laughlin, a professor of astronomy and astrophysics at the University of California, Santa cruz, who did not contribute to the new study.

#Planck snaps infant Universe For astronomers, it is the ultimate treasure map. On 21 march, the Planck space telescope team released the highest-precision map yet of the cosmic microwave background (CMB),

NASA/WMAP SCIENCE TEAMIT was not until the launch of the Cosmic Background Explorer (COBE) spacecraft that astronomers could begin to see variations in the background, at levels of 1 part in 100,000.

and universe expansion Astronomers have had long a dark secret: one of the cornerstones of the Nobel prizewinning discovery that the expansion of the universe is accelerating had never been tested directly.

In 1998 astronomers used measurements of the distances of various type IA supernovae to show that the expansion of the universe is accelerating

which could change the way astronomers interpret these supernovae in the future. In the favoured model called the single degenerate system a white dwarf reaches its critical mass by stealing material from an ordinary companion star.

but astronomers would have to account for multiple types of supernovae. One has to care about this

Astronomers have found a handful of planets that orbit both partners in close binary pairs.

An analysis led by astronomer Paul Robertson at Pennsylvania State university concluded that Gliese 581 d and g two of the first potentially habitable worlds ever found are created actually illusions by sunspots on the parent star.

It has a radius slightly more than double that of Earth's a size that led astronomers to assume it was a shrunken version of gassy planet Neptune

In December astronomers announced hints of watery plumes spurting from Jupiter's large moon Europa potentially giving us a peek into a vast ocean likely to exist beneath its ice.

Most astronomers thought that the plumes force their way out through cracks in an icy crust sitting over a sea of liquid water.

but astronomers suspect that this is an unusual episode. We are looking at Enceladus at a wonderful special time where it's very active

At the same time a stream of particles blowing out from the sun the solar wind inflates a bubble of plasma around the solar system called the heliosphere Astronomers have assumed long that the sun's motion through the galaxy squashes

Using the first three years of observations from NASA's Interstellar Boundary Explorer (IBEX) spacecraft astronomers were able to map this heliotail for the first time.

It's hoped that this will help astronomers to gain a better understanding of galaxy formations, aid in tracking potentially dangerous asteroids,

The new planet is called 51 Eridani b. The GPI is a new astronomy instrument operated by an international collaboration headed by Bruce Macintosh, a Professor of Physics in the Kavli Institute at Stanford.

"The astronomers use adaptive optics to sharpen the image of a star, and then block out the starlight.

To date, the astronomers have looked at nearly 100 stars.""51 Eridani is only 20 million years old,

Once the astronomers zeroed in on the star, they blocked its light and spotted 51 Eridani b orbiting a little farther away from its parent star than Saturn does from the sun

"All of the exoplanets astronomers have imaged before have atmospheres that look like stars very cool stars, but still stars,"says Macintosh,

For years, astronomers have devised telescopes that, in theory, can use light to help them unravel the mysteries of the universe.

"Light is everything in astronomy--it's the carrier of almost all information and knowledge we have of the universe,

Astronomers have identified more than 1700 exoplanets some as far as hundreds of light years away. Most were discovered by the traditional transit method

From this information astronomers will be able to determine whether distant exoplanets they discover are rocky worlds like Earth or less dense gas giants like Jupiter.

The method is precise enough to help astronomers identify Earthlike planets in the habitable zone the orbital distance sweet-spot where water exists as a liquid.

Their new version of the astro-comb lets astronomers measure green light --which is better for finding exoplanets.

Astronomers have attempted to get around this by combining many images, each just a few degrees wide, that cover different areas of the sky.

But astronomers very well know that many interesting events occur on much shorter timescales, such as the transit of exoplanets across other stars, binary stars that eclipse, gamma ray bursts and so on.

This will allow astronomers to examine the relevant area of sky in the days, weeks or even months before supernovas or gamma ray bursts, looking for interesting precursor events.
