And Ethiopia#one of the world's poorest countries#has unveiled two new telescopes atop a mountain on the outskirts of Addis ababa

Colorado where the mirrors for the $8. 7 billion James webb space telescope (JWST) are being built and tested.

On tables inside these, sit some of the 18 individual hexagonal mirrors that make up the massive 21ft (6. 5m) diameter primary mirror of this new space telescope."

like the Hubble space telescope, the JWST will be launched into space with its mirror out of focus. Only this time, unlike when Hubble was launched,

This puts additional pressure on the teams of scientists and engineers around the world who are working on this international space telescope,

The telescope will be operating in deep space, at a temperature of#243c(#405f. That's only 30c (86f) above absolute zero, the lowest possible physical temperature.

the telescope will be launched into space with deliberately bumpy mirrors and out of focus optics. The progress of the JWST has been slow and costly.

The key instruments for the telescope have been tested and delivered, the structure completed and the (folding) tennis-court sized heat shield finalised.

or European Extremely Large telescope. With a mirror that is 39 metres (128ft) in diameter, the E-ELT will dwarf all existing optical telescopes

#and those planned to appear in the next decade or two. And it won't just bring plenty of life to this corner of the Atacama.

an organisation that already operates a number of telescopes in the Chilean desert. Two of the more high-profile planet hunters have hit rocky ground in recent months, however.

#but two of its four reaction wheels that control the telescope's direction have failed in recent months,

spotting them is tricky with existing ground-based optical telescopes.""It's like trying to see the light from a feeble little LED 10cm away from a stadium floodlight,

The bigger the mirror, the sharper the image a telescope can capture, and the dimmer the objects it can detect.

Hence it takes an extremely large telescope to try to spot any planets that may support alien life many light years away.

Currently, the world's largest ground-based optical telescope is Gran Telescopio Canarias in the Canary islands

other telescopes are busy scanning the skies for faraway worlds. About an hour's dusty and boulder-strewn drive away from Armazones is another telescope,

whose four huge towers resemble some kind of factory rather than a scientific facility. It is the VLT

#or Very Large telescope, composed of four individual 8. 2m (26. 9ft) mirrors#based at Cerro Paranal,

But even with these adaptive optics tools, existing ground-based telescopes can only"see#planets bigger than Jupiter#gas giants that orbit their parent stars at a huge distance.

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.

the Giant magellan telescope (GMT) in Las Campanas Observatory in Chile, and the Thirty Meter Telescope (TMT) on Mauna kea in Hawaii.

The GMT will have seven 8. 4m (27. 6ft) mirrors, arranged like flower petals. Together they will make up a primary mirror 24. 5m (80. 4ft) in diameter.

Telescopes can produce much clearer images in space, free from our turbulent atmosphere. The Hubble space telescope has been circling Earth

since 1990 and has spotted a few planets #and also helped determine what some extra-solar worlds are made probably of.

says Matt Mountain, the director of the Space telescope Science Institute at Nasa. Hubble's planned successor, the James webb space telescope (JWST)# set to go into orbit around 2018#is expected to do much more.

Equipped with a 6. 5-metre (21ft) diameter mirror JWST will have a variety of tasks,

The telescope will aim to find out whether these extra-solar worlds are so-called"super-Earths##rocky planets that could potentially be habitable#or miniature versions of Neptune,

or space-based telescopes.##Sic transit gloriaas exciting as the plans for direct imaging are,

One such device, the High accuracy radial velocity planet searcher (Harps), is mounted on a 3. 6m-(11. 8ft-)mirror telescope at La Silla, another one of ESO's observatories in the Atacama.

"The big ground-based telescopes can work with it and do the spectroscopy, #says Macintosh."

you can then use the James webb space telescope to measure the composition of its atmosphere.##But to really find a habitable Earth-twin orbiting a star just like our Sun,

he adds#with a giant telescope fully designed for planet hunting and equipped with a mirror of eight metres or more.

called the Advanced Technology Large Aperture Space telescope (ATLAST), a space telescope with a 8-to-16m mirror that would be 2, 000 times more light-sensitive than Hubble.

If all goes according to plan, ATLAST could be launched between 2025 and 2035. The fact that there have been few good candidates for planets that host life found so far should not discourage the searchers The data already collected suggests that there are about 100 billion planetary systems in our galaxy alone,

The array of radio telescopes works together to form a gigantic yepeering into the cosmos. nderstanding the production of organic material at the early stages of star formation is critical to piecing together the gradual progression from simple molecules

For the new study published in the Monthly Notices of the Royal Astronomical Society researchers used the Very Large telescope in Chile

and Hubble space telescope observations of the nearest examples of these calcium-rich transients to attempt to detect anything left behind or in the surrounding area of the explosion.

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.

The Hubble observations used 96 hours of telescope time spread over 11 months. This was the largest Hubble program ever devoted to studying a single exoplanet.

I think it s very exciting that we can use a telescope like Hubble that was designed never with this in mind do these kinds of observations with such exquisite precision

The first spectra which Bean obtained in 2010 using a ground-based telescope suggested that the planet s atmosphere either was predominantly water vapor

The launch of NASA s next major space telescope the 6. 5m James webb space telescope (JWST) later this decade should reveal more about such worlds Kreidberg says. ooking forward JWST will be transformativeshe says. he new capabilities

of this telescope will allow us to peer through the clouds on planets like GJ 1214b.

Using the South pole Telescope scientists observed twisting patterns in the polarization of the cosmic microwave backgroundâ##light that last interacted with matter very early in the history of the universe less than 400000 years after the big bang. These patterns

Whereas giant Jupiter-size planets often exert a gravitational tug on their host stars that is detectable with Earth-based telescope spectrographs,

On 21 march, the Planck space telescope team released the highest-precision map yet of the cosmic microwave background (CMB),

Eugene Churazov of the Max Planck Institute for Astrophysics in Garching Germany and colleagues observed SN 2014j with the INTEGRAL gamma-ray telescope.

Miguel Pérez-Torres of the Institute of Astrophysics of Andalucia in Granada Spain and colleagues used the European VLBI Network of radio telescopes spread across Europe and China to study SN 2014j.

Kepler-10c was discovered in 2011 by NASA's Kepler space telescope. The planet orbits a star that is about 560 light years away from us.

Now Xavier Dumusque of the Harvard-Smithsonian Center for Astrophysics in Cambridge Massachusetts and his colleagues have used the HARPS-N telescope in the Canary islands to pin down Kepler-10c's mass.

But the team checked for a bevy of possible errors that might have been caused by the telescope itself

when the Hubble space telescope stared at one spot in the sky for nearly 12 days. The code also managed to reproduce different types of galaxies including spiral galaxies like the Milky way and blob-shaped elliptical galaxies.

The supernova PS1-10afx was discovered in 2010 using the Pan starrs telescope in Hawaii. Because it was so much brighter than normal it sparked controversy over

On 17 march researchers led by John Kovac of Harvard university announced that gravitational waves from the early universe had been found by a telescope called BICEP2 at the South pole.

To minimise the chances of this effect causing a false signal the BICEP 2 team pointed their telescope at a patch of sky far away from the Milky way's dusty disc.

A handful of nearby dust shells can be seen by radio telescopes appearing as giant loops looming above the Milky way's galactic disc.

and the giant loops detected by radio telescopes (blue lines). The effect of this finding on the BICEP2 result is not clear

Starlight captured by the Kepler space telescope has revealed that the amount a star flickers is tied to its size offering a better way to measure a wide variety of stars and their associated planets.

The telescope's vigil required exquisite targeting precision and key parts of its steering system are broken now ending the telescope's main mission as an exoplanet hunter.

But you haven't heard the last of Kepler. Two years'worth of data still need inspecting including information about the thousands of stars in its field of view.

This new approach could ultimately lead to advances in solar photovoltaics, detectors for telescopes and microscopes,

The findings could also prove useful in optical systems, such as microscopes and telescopes, for viewing faint objects that are close to brighter objects for example, a faint planet next to a bright star.

And the ground receiver is based on arrays of small inexpensive telescopes that are coupled fiber to highly efficient superconducting nanowires a photon counting technology that was brought to its high state of maturity by joint MIT and Lincoln Lab teams.

One example of a use for the material is in telescopes to increase the instruments'ability to see very faint stars.

For example it reduces stray-light improving the ability of sensitive telescopes to see the faintest stars

#In Japan, Eight People With Two Laptops Launch A Telescope Into Orbit A new low-cost highly automated rocket from Japan's space agency launched Saturday with just eight crew members and two laptops on-site.

The Japan aerospace exploration agency sent the first of its new generation of launch vehicles into orbit carrying a telescope that will observe the atmospheres of Venus Mars and Jupiter.

The telescope's measurements will provide astronomers with clues to events early in the solar system's history according to the agency's description of the project.

and the small satellite carrying the planet-viewing telescope so that it could launch more missions more frequently.

The telescope was identified in the Pan-STARRS 1 wide-field survey telescope in Maui. Follow-up observations were performed with several other Hawaii-based telescopes including the NASA Infrared telescope Facility the Gemini North Telescope and the Canada-France-Hawaii Telescope.

The discovery will soon be detailed in Astrophysical Letters but for now you can read the prepublished verison on Arxiv.

Altogether-without the smartphone-the cost of building the telescope is just $312. In an interview with Science Magazine

With this information the telescope is able to direct itself towards various objects in space including planets, galaxies, asteroids and stars automatically.

Parr and the OSA team sees the potential for a distributed network of telescopes across neighborhoods around the world.

The limitations of early telescopes led to questions about the accuracy of the constant counting of sunspots for the last 300 years, leading to the Group Sunspot number being started in 1998.

-and fading steadily, according to the results of a survey using seven of the world's most powerful telescopes.

Researchers collated data from the world most powerful telescopes, including the VIST and the VST at Chile Paranal Observatory, Nasa GALEX, WISE and a European space agency Herschel telescope.

In an unprecedented collection of data, they aimed to map and model all of the energy generated in the universe today.

#How to Build an Evryscope One problem with telescopes is that they can only peer at a tiny piece of sky at any one time.

Indeed, this instrument represents an entirely new type of telescope which Law and co call the Evryscope, from the Greek for ide-seeing.

It consists of 23 small telescopes mounted on a hemispherical dome that can rotate to track the sky.

Each small telescope has a 7 cm aperture and a field of view of a few hundred square degrees.

so that the fields of view of each of the small telescopes overlap to cover around 10,000 square degrees of sky simultaneously

The small telescopes themselves are simplessentially camera lenses sitting on top of CCD chips. Law and co have been experimenting with Canon 50mm and 85mm F/1. 2 lenses.

And theye had two telescopes with these lenses operating automatically in the Arctic over the last two winters.
