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

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

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,

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.

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.

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.

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

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,

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."

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

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

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

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

For the study published in Physical Review Letters researchers used the first data from SPTPOL a polarization-sensitive camera installed on the telescope in January 2012. he detection of B-mode polarization by South pole Telescope

But just two days later, telescopes on the probes revealed the emergence of an additional,

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

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

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.

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.

#Open Space agency gears up to launch open source 3d printed telescope For those of us who love space

wel soon be able to just 3d print our own high-powered automated robot telescopes right at home.

Thanks to the efforts of Parr and his team, the OSA Ultrascope automated robot telescope kit is extremely cheap to produce

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

Although Parr and OSA first announced the 3d printed telescope project back in 2014, they have spent the past year further refining the design and performing a number of beta tests.

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.

The data from that study, using the ESO Very Large telescope in Chilie, seemed to indicate that water persisted on the surface of the Red planet for at least a billion years.

the new camera is at the heart of the 8. 4-meter (27.5-ft) Large Synoptic Survey Telescope (LSST) now under construction atop Cerro Pachón in Chile.

Even though a telescope is needed not to view a meteor shower your local observatory might have people on hand to tell you more about skywatching.

You may even get a chance to look at other celestial objects through a telescope. Check with local observatories for details.

"However, the experiment at the Canary islands involved a telescope on top of one mountain and a telescope on top of another mountain,

with the telescopes pointed at each other at night, since background light during the day would interfere with the experiment,

After GPI was installed on the 8-meter Gemini South Telescope in Chile, the team set out to look for planets orbiting young stars.

and ground-based telescopes we could get our hands on to measure the energy output of over 200,000 galaxies across as broad a wavelength range as possible,

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

and instrument designs that could make better use of the light collected by telescopes, "Escuti says."

his team has provided the astronomers with geometric phase holograms that they have used build advanced coronagraphs--telescopes that can see things close to stars--to study exoplanets beyond our solar system."

They plan to find the second planet again using a powerful new optical device installed on the Italian National Telescope that will measure Venus'precise gravitational pull on the sun

We are building a telescope that will let us see the sun the way we would see other stars said Phillips who is a staff scientist at the Harvard-Smithsonian Center for Astrophysics.

The Harvard-Smithsonian team is installing this device on the High-Accuracy Radial Velocity Planet Searcher-North (HARPS-N) a new spectrograph designed to search for exoplanets using the Italian National Telescope.

We will look at the thousands of potential exoplanets identified by the Kepler satellite telescope by the transit method.

--and the 100-meter Green Bank Telescope in West virginia showed the presence of lumps in the image of Sagittarius A*.Recent upgrades have increased greatly the sensitivity of these telescopes.

The team then used the Submillimeter Array and the IRAM submillimeter telescope to search in RW Leo,

#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.
