A New Telescope That Could Allow Exoplanets To Be Photographed For The First Time



Could Flower Power Spot Alien Life? Nasa Reveals Giant Space Sunflower That Could Allow Exoplanets To Be Photographed For The First Time -- Daily Mail

* Nasa project could allow pictures of exoplanets to be taken clearly
* Flower would act as a starshade to block light from stars - but allow telescopes to see their exoplants

It may look like a giant sunflower blooming, but in fact this is Nasa's latest attempt to photograph an alien planet capable of sustaining light.

The unfurling flower can block light from a star, allowing space telescopes to get a clear view of planets orbiting it.

Experts hope the invention could revolutionise our knowledge of alien planets

Building 'Super Telescopes' Is The New Space Race

The race will see sophisticated observatories built on top of mountains in Hawaii and Chile in an attempt to see the wonders hiding in the outer reaches of the cosmos

New Space Race Begins: Astronomers Compete To Build Next Generation Of 'Super-Telescopes' To Reveal The Hidden Universe -- Daily Mail

* Huge observatories will be built on top of mountains in Hawaii and Chile
* These include the Giant Magellan Telescope, the Thirty Meter Telescope and the European Extremely Large Telescope
* Astronomers hope to use these super-telescopes to look at the first stars
* They also plan to uncover life-threatening asteroids heading towards the planet and spot Earth-like worlds

A new space race is heating that could help unravel some of the biggest mysteries of the universe.

Astronomers around the world are going head to head to develop three major telescopes that will be at least 10 times more powerful than anything in operation today.

The race will see sophisticated observatories built on top of mountains in Hawaii and Chile in an attempt to see the wonders hiding in the outer reaches of the cosmos.

Advances In Telescopes Will Make It Possible To View Exoplanets By Hiding Interfering Starlight

Sifting Starlight These two images show HD 157728, a nearby star 1.5 times larger than the sun. The star is centered in both images, and its light has been mostly removed by an adaptive optics system and coronagraph belonging to Project 1640, which uses new technology on the Palomar Observatory's 200-inch Hale telescope to spot planets.

New Telescope Optics Can Directly View Exoplanets By Hiding Interfering Starlight -- Popular Science

For now, the thousands of potential exoplanets discovered in the past two years are little more than curvy dips on a graph. Astronomers using the Kepler Space Telescope pick them out by examining the way they blot out their own stars’ light as they move through their orbits. But if astronomers could block out the stars themselves, they may be able to see the planets directly. A new adaptive optics system on the storied Palomar Observatory just started doing that — it’s the first of its kind capable of spotting planets outside our solar system.

Super Telescope 'Favours South Africa Over Australia'

The Square Kilometre Array will take to the middle of the next decade to finish

Super Telescope 'Favours South Africa Over Australia' -- BBC

Australian media are reporting that the country is running behind South Africa in the selection process for the Square Kilometre Array (SKA).

The huge £1.3bn ($2bn) radio telescope facility is being designed to answer some key questions about the Universe.

The Saturday editions of the Sydney Morning Herald and The Age carried a leak from a panel that has looked at the technical strengths of each bid.

But commentators said South Africa's selection was not yet a done deal.

My Comment: That's one expensive telescope. My money is on Australia, with the reason being that it is more politically stable than South Africa.

India To Build World's Largest Solar Telescope

Photo: Currently, the world's largest solar telescope is the McMath-Pierce Solar Telescope, with a diameter of 1.6 metres in Kitt Peak National Observatory at Arizona in the US.

From Space Daily:

India is inching closer towards building the world's largest solar telescope in Ladakh on the foothills of the Himalayas that aims to study the sun's microscopic structure.

The National Large Solar Telescope (NLST) project has gathered momentum with a global tender floated for technical and financial bidding by the Bangalore-based Indian Institute of Astrophysics (IIA).

PHOTOS: World's Largest Telescope Unveiled


From National Geographic:

August 6, 2009--A low-hanging sun brightens the fields around the dome of the Gran Telescopio Canarias, or GTC, the latest addition to the handful of Earth-based optical telescopes designed to study the heavens.

Crowds gathered last week on the island of La Palma in the Canary Islands--a Spanish territory--to watch Spanish King Juan Carlos inaugurate the U.S. $180-million GTC, which is co-owned by Spain, Mexico, and the University of Florida in the U.S.

Hawaii Chosen To Host World's Largest Telescope

From RIA Novosti:

MOSCOW, July 22 (RIA Novosti) - The world's largest telescope, which could offer a glimpse into the beginning of the universe, will be built on top of the dormant Mauna Kea volcano in Hawaii, a consortium of U.S. and Canadian universities has announced.

The Thirty Meter Telescope (TMT), named for the diameter of its primary mirror, will be able to detect light that has taken 13 billion years to reach the Earth, effectively allowing scientists to see pictures of the past, such as how stars and galaxies were formed in the early years of the universe.

The Future Of 5 Telescopes In Space

(Photograph by NASA/AFP/Getty Images)

From Popular Mechanics:

This week has been an active one for earthlings' quest to understand the universe. Here is the big news on five telescopes in the sky.


On what is supposed to be the last space shuttle visit ever to the Hubble Space Telescope, astronauts successfully installed a new camera.

Mission specialists John Grunsfeld and Drew Feustel installed the Wide Field Camera 3, an upgraded system that will produce larger, more detailed photos over a wide range of colors, according to NASA. The old camera, responsible for some of the most images of the cosmos since its installation in 1993, will be brought down for display at the Smithsonian's National Air and Space Museum.

World's Largest Telescope Will Search Heavens For Habitable Planets Like Earth

Mission Incredible: The Extremely Large Telescope will be even more powerful than the Very Large Telescope, pictured here.

From The Telegraph:

A giant telescope powerful enough to identify habitable planets like Earth in distant solar systems is to be built by scientists.

The European Extremely Large Telescope will be the first optical telescope capable of picking out the weak pinpricks of light that are reflected from planets as they orbit stars.

Astronomers claim the huge instrument, which will house a mirror the width of five double decker buses placed end to end, will be able to spot rocky Earth-like planets up to 100 million million miles away.
