An extraordinary time to be conducting SETI observations

December 8, 2011

SETI

The Allen Telescope Array (ATA) - Credit: SETI

Telescopes at SETI (Search for Extraterrestrial Life) are once again operational and searching planetary systems for signals of possible extraterrestrial intelligence. Great news I know, better still some of its first targets are the exoplanet candidates recently discovered by NASA’s Kepler space telescope.

SETI’s Alan Telescope Array (ATA) had been in hibernation since April following the withdrawal of the SETI Institute’s former partner, U.C. Berkeley – the operator of the observatory in California where the ATA is located – due to budgetary shortfalls (yawn yawn).

New funding has recently been acquired for observatory operations allowing the ATA to resume observations and work to examine the thousands of new candidate planets found by Kepler, with the highest priority given to the worlds discovered that are located in their star’s habitable zone.

Resuming observations was possible thanks to the interest and generosity of the public who supported the institute’s research via the SETI website with additional funds being provided by the United States Air Force as part of their formal assessment of the instrument’s utility for Space Situational Awareness.

From Jill Tarter, Director of SETI Research: We are exploring once again, with renewed enthusiasm.  While our work with the US Air Force to try to avoid future collisions in space will insure that the array is maintained in good operating condition, we will continue to have to raise the funds to conduct our SETI observations.

Awesome news! visit SETI here to find out more, donate too should you support the cause.

Astronomy Events – November 2011

October 31, 2011

by yaska77

It’s been a little quiet here of late, but we’re hoping better weather is on the way. It can’t be cloudy all the time right?!

That said, October was actually one of our best ever months for observing, we even got the best images we’ve taken with our own equipment so far! Most of them came about from astro events we listed, so here is a list of upcoming astronomy events for November to whet your appetites.

Tuesday 1st November – The Great Red Spot on Jupiter will be visible through a good telescope on the central median line around 21:15 (UTC/GMT) tonight, but also on a number of nights throughout November (see comments below for more info)

Jupiter is only just past opposition so is visible in the night sky all night long for the whole month. A telescope or good pair of binoculars will help show the four brightest Galilean moons (first discovered by Galileo in January 1610), which can be seen stretched out in a line in our photograph below

Wednesday 2nd November -  First quarter Moon

Saturday 5th November – Tonight is the peak of the Southern Taurid meteor shower. Because of the gravitational effect of planets (particularly Jupiter) the Taurids have become spread out over time, allowing separate streams known as the Southern Taurids and Northern Taurids to be observable on different dates

Tuesday 8th November – Moon at Apogee (406,180 km), the farthest point it reaches on it’s orbit around the Earth. Asteroid 2005 YU55 will make a close pass by the Earth today (closer than the orbit of the Moon) but poses no danger

Thursday 10th November – Full Moon, sometimes called the Beaver Moon or Dark Moon

Saturday 12th November – This evening sees the peak of the Northern Taurid meteor shower, however the recent full Moon (which is very close to the radiant) will obscure all but the brightest ones

Thursday 17th/Friday 18th  November – Leonid meteor shower peaks tonight but the waning Moon may be in the way. Its light will block out a lot of the fainter meteors but you should still see some in darker parts of the sky

Friday 18th November – Last quarter Moon

Wednesday 23rd November – Moon at Perigee (359,690 km), the closest point of its orbit around the Earth. As it doesn’t rise until around 05:15 UTC/GMT (and will be only 5% lit) it won’t interfere if you fancy having a look at some deep sky objects.

Orion will be well above the horizon by 22:00 and our perennial favourite M42 (the Orion Nebula) should be a great sight through binoculars or a small telescope. Located in the sword hanging from Orion’s belt, we managed to get a good look at it in October (it’s one of the autumn constellations we always take a peek at when the skies are clear!)

In the brightest part of the Nebula you can see the four stars that make up the "Trapezium Cluster" (click to enlarge) - Credit: Sky-Watching/A.Welbourn

Friday 25th November – New Moon and partial Solar eclipse, though it will only be visible from Antarctica and parts of the Southern Ocean

Sunday 27th November – Saturn is making a welcome return to our skies, and can be see before dawn (rising just before 04:00 UTC/GMT) to the East near the bright star Spica, part of the constellation Virgo

Remember, it can take your eyes up to 20 minutes to become properly dark adapted, and anything up to an hour for a telescope to reach ambient temperature outside (to ensure the best image), so give yourself plenty of time to get set up!

We’ve also added the “Monthly Guide” section in the menu bar to the right (where this guide will appear), so next time you visit you can find it again easily!

Astronomy Events – October 2011

September 30, 2011

by yaska77

Here is a list of upcoming Astronomy events for October. The recent clear warm nights at the end of September have given us the chance to get a look at a few things, but the sky is so big! How do you choose!? Well, this latest guide might just have a few suggestions of interest.

Saturday 1st October – In the early hours of 1st and 2nd October the planet Mars can be found right in front of Praesepe (the Beehive Cluster, Messier 44), in the constellation Cancer. Should be great to see with binoculars or a small telescope!

You can see what this actually looked like in our photographs here  (and compare it to the guide image below!), it was one of many targets on what turned out to be a great night!

Tuesday 4th October -  First quarter Moon

Saturday 8th October – The annual Draconid meteor shower (also known as the Giacobinids) should reach its peak this evening (the height of activity expected between 16:00 and 22:00 UTC/GMT), with calculations suggesting we could be in for an outstanding display. The ZHR (Zenithal Hourly Rate) could range from a few tens of meteors per hour to several hundred

The image below can help guide your eyes, but if it’s as busy as forecasts are suggesting you should see them all over the sky, despite a bright Moon to the south. It might wash out some of the fainter meteors but you should still see the brighter flashes. Draconid meteors are also known to be very slow moving

The location in the night sky Draconid meteors will appear to originate from

Tuesday 11th/Wednesday 12th October – Full Moon and Moon at Apogee (406,435 km), the farthest it gets away from the Earth during it’s orbit. This full Moon is sometimes known as the Hunter’s Moon or Blood Moon (occurs at 02:05 GMT)

Thursday 13th October – The planet Saturn is in superior conjuction on the far side of the Sun, so will be unobservable throughout October

Monday 17th October -  Tonight should see the start of the annual Orionids meteor shower (17th-25th). The Orionids are considered a universal sky-watching opportunity as the radiant point is close to the celestial equator, meaning both hemispheres (northern and southern) will see some of the display not lost in the Moon’s glare. The peak should be on 21st October with a ZHR of around 20-25 per hour

Thursday 20th October – Last quarter Moon. It won’t rise until after midnight so a good chance earlier on to maybe catch a few meteors

Wednesday 26th October – New Moon and Moon at Perigee (357,050 km), the closest point of its orbit around the Earth.

Saturday 29th October -  Jupiter is at opposition in the constellation Aries, meaning it is in the opposite side of the sky to the Sun, and will appear at it’s brightest

Sunday 30th October -  British Summertime ends at 02:00 BST, when the clocks go back 1 hour to 01:00 GMT (but at least I get an extra hour in bed!)

Remember, it can take your eyes up to 20 minutes to become properly dark adapted, and anything up to an hour for a telescope to reach ambient temperature outside (to ensure the best image), so give yourself plenty of time to get set up!

We recently added the “Monthly Guide” section in the menu bar to the right (where this guide will appear), so next time you visit you can find it again easily!
