Just as microscopes and telescopes help researchers see more about the world microphones can help them learn more about their surroundings via sound.

The telescope is designed to examine dust grains in young star systems and was inaugurated officially this year.

and balancing my telescope. The sounds of owls and night birds filled the air. Shivering from the cold I scanned the sky with binoculars until BAM!

Slewing the telescope I began to make my images. Tracking the pair I made many images.

if you have a telescope or you're some place that actually gets dark that all the stars that you see in the sky aren't necessarily all there.

On September 7 2013 Australian Terry Lovejoy using an 8-inch Schmidt-Cassegrain telescope discovered what would be designated comet Lovejoy.

This would be the test image for my newly modified telescope. As the night wore on

Slewing my telescope (moving to aim at a point in the sky) I found the comet in a 2-inch-wide-angle eyepiece one that gave

I then slipped the diagonal a device that that makes it easier to use refracting telescopes

and replaced it with a digital single-lens reflex (DSLR) camera refocusing carefully on the faint glowing orb that was Lovejoy.

Colorado, and his colleagues used the Keck telescope on Mauna kea, Hawaii, and the Anglo-Australian Telescope in Siding Spring in Australia to look for atomic

or molecular sodium both in the plumes and in one of Saturn's rings thought to be fed by these plumes, the E ring.

then they would throw up salt-rich jets giving out a strong sodium signal that could be spotted by ground-based telescopes.

because the small amounts of sodium he would expect to see would not be detectable using the Keck telescope.

To secure funding from the space agency, the Kepler team will have to show that the studies could not be done by other telescopes.

and the telescope s focus will drift. Over time, starlight will start to fall on different pixels with slightly different sensitivities."

By observing microlens planets using Kepler and ground-based telescopes at the same time, differences in transit duration and brightness emerge that can yield the planets mass.

what terrestrial telescopes can accomplish. Telescopes only work at night which prevents us from seeing asteroids approaching the planet from the inside of Earth's orbit.

Also many asteroids are dark black and reflect less than 10 percent visible light making them hard to spot from Earth.

And even if people had missed somehow an exploding star that star's remnants would still be out there today giving out a faint glow that could be picked up by telescopes.

#Dusty surprise around giant black holeeso's Very Large Telescope Interferometer has gathered the most detailed observations ever of the dust around the huge black hole at the centre of an active galaxy.

But new observations of a nearby active galaxy called NGC 3783 harnessing the power of the Very Large Telescope Interferometer (VLTI) at ESO's Paranal Observatory in Chile 2 have given a team of astronomers a surprise.

In order to investigate the central regions of NGC 3783 the astronomers needed to use the combined power of the Unit Telescopes of ESO's Very Large Telescope.

Using these units together forms an interferometer that can obtain a resolution equivalent to that of a 130-metre telescope.

which will allow us to combine all four VLT Unit Telescopes at once and observe simultaneously in the near-and mid-infrared--giving us much more detailed data.

Bean and his colleagues have made the best observations of planetary atmospheres so far using the Hubble Telescope the Spitzer Space Telescope and in Chile the Very Large Telescope array and the twin Magellan Telescopes.
