http://spaceweather.com

SPACE STATION IN CONSTANT SUNLIGHT: For the next few days, the International Space Station (ISS) will be orbiting Earth in constant sunlight. This sets the stage for a remarkable sky show. Because the ISS is constantly illuminated, it shines brightly in the night sky every single time it passes overhead. Some observers can see the space station 3, 4, even 5 times a night. More information and flybys predictions may be found at http://spaceweather.com

ANDROID FLYBYS: Spaceweather's "Simple Flybys" app is now available for Android phones as well as the iPhone and iPad. Details at http://simpleflybys.com

WEEKEND LUNAR ECLIPSE: On Saturday, June 26th, the Moon will pass through Earth's shadow, producing a 54% partial lunar eclipse. The event is visible from most of the Americas, Australia, Japan, east Asia and all of the Pacific Ocean. For readers in the USA, the best time to look is just before sunrise on Saturday morning.

New Comet McNaught

Space Weather News for June 8, 2010
http://spaceweather.com

NEW COMET McNAUGHT: A fresh comet is swinging through the inner solar system, and it is brightening rapidly as it approaches Earth for a 100 million mile close encounter in mid-June. Comet McNaught (C/2009 R1) has a vivid green head and a long wispy tail that look great through small telescopes. By the end of the month it could be visible to the naked eye perhaps as bright as the stars of the Big Dipper. Because this is the comet's first visit to the inner solar system, predictions of future brightness are necessarily uncertain; amateur astronomers should be alert for the unexpected.

X-37B Sighting and Aurora

Space Weather News for May 25, 2010
http://spaceweather.com

X-37B SIGHTINGS: Amateur satellite watchers have spotted a US Air Force space plane similar in appearance to NASA's space shuttle circling Earth in a heretofore secret orbit. Known as the "X-37B," it can be seen in the night sky shining about as brightly as the stars of the Big Dipper. Flyby predictions and more information may be found at http://spaceweather.com .

Would you like to turn your iPhone into an X-37B tracker? There's an app for that: http://simpleflybys.com .

AURORA WATCH: A magnetic filament on the sun erupted yesterday (May 24th), and the blast hurled a coronal mass ejection in the general direction of Earth. High-latitude sky watchers should be alert for auroras around May 27th when the advancing cloud is likely to deal a glancing blow to our planet's magnetic field.

Final Voyage of Space Shuttle Atlantis

Received this from my friend Matt,


----------------------------------


CAPE CANAVERAL, Fla. – Space shuttle Atlantis thundered away on its final voyage to orbit Friday, hoisting an experienced crew of six and a full shipment of space station gear.


Atlantis sped through a perfectly clear afternoon sky, blazing a trail over the Atlantic before huge crowds eager to catch one of the few remaining shuttle launches. More than 40,000 guests — the biggest launch-day crowd in years — packed the Kennedy Space Center.


The shuttle's destination is the International Space Station, which was soaring over the South Pacific at the time of liftoff. The shuttle should catch up with the orbiting complex and its six residents Sunday morning.


A piece of orbiting junk, however, was threatening to come too close to the space station. If necessary, Mission Control will order up a maneuver so the station can dodge the debris the night before Atlantis' arrival. The docking will not be delayed, even if the station has to move out of the way of the unidentified piece, NASA officials said.


"Good luck, godspeed and have a little fun up there," launch director Mike Leinbach told the astronauts just before liftoff. He said he was speaking on behalf of all those who have worked on Atlantis since construction began in 1980.


"Like you said, there are thousands of folks out there who have taken care of this bird for a long time," replied commander Kenneth Ham. "We're going to take her on her 32nd flight, and if you don't mind, we'll take her out of the barn and make a few more laps around the planet."


The astronauts — all repeat space fliers and all men — couldn't resist a little humor before they got down to business. They showed up for their steak and cheeseburger breakfast wearing blue and black smoking jackets, white shirts and black bow ties.


This 12-day mission is the last one planned for Atlantis, the fourth in NASA's line of space shuttles. Only two flights remain after this one, by Discovery and Endeavour. NASA plans to end the 30-year program by the end of this year.


Atlantis — which rocketed into orbit for the first time in 1985 — is loaded with fresh batteries and a Russian-built compartment for the space station. The 20-foot-long module is crammed with food, laptop computers and other U.S. supplies.


Ham and his men will install the compartment on the space station, and carry out three spacewalks to replace six old batteries and hook up an antenna and other spare parts.


Alexey Krasnov, chief of the Russian Space Agency's piloted program, said it was a miracle that Atlantis took off without any delays.


"It looks like that Atlantis is telling us, `Please use me again. I am capable,' " he said, smiling. "Maybe two-thirds of the launches were postponed by the weather or hardware ... and today it worked exactly as planned."


Only a few small bits of insulating foam were seen coming off the fuel tank during liftoff, nothing significant, officials said.


Launch spectators included Defense Secretary Robert Gates and late-night TV host David Letterman, as well as dozens of Russians. About 150 Twittering guests watched from Kennedy's media complex.


Matt Balan, 29, of Alexandria, Va., lost his network connection right at liftoff as he was trying to tweet. He finally got this message out a few minutes after the fact: "That was spectacular!!!!"


Even off-duty astronauts marveled at the sight of Atlantis rising one last time, snapping pictures with their cell phones. "That was an incredible launch," said Rick Mastracchio, who flew last month on Discovery. Some Apollo astronauts also showed up.


President Barack Obama wants NASA to focus on getting astronauts to an asteroid by 2025 and into orbit around Mars by 2035. He canceled the previous administration's plan to return to the moon.


Friday's launch was NASA's fourth shuttle liftoff in six months. Now the pace will slow a bit. Discovery isn't due to fly until September, followed by Endeavour in November — at the earliest.


There's a chance that Atlantis could fly again after it returns to Earth on May 26. The shuttle will be prepped in case a rescue mission is needed for the last flight, by Endeavour. Assuming there's no emergency, Atlantis could be used for another supply run if the White House approves it, and that would close the shuttle program for good. Then the shuttles would head off to museums.


Immediately after watching liftoff, U.S. Sen. Bill Nelson, D-Fla., told The Associated Press that he's encouraging one more flight for Atlantis and noted: "There's a good chance the president will approve it." He flew Columbia into orbit in 1986.


NASA's space operations chief, Bill Gerstenmaier, said he'd be glad to fly Atlantis in June 2011 with a minimal crew of four, if money is forthcoming. He estimates it would cost between $600 million and $1 billion to keep the shuttle program going beyond January.


Under the Obama plan, NASA astronauts will hitch rides to the space station on Russian Soyuz rockets for the near future.


NASA expects to keep the space station running through 2020.

9 Planets Found

Received from Matt:

Astronomers find 9 new planets and upset the theory of planetary formation

from http://www.eurekalert.org/pub_releases/2010-04/uoc--afn041310.php


(Santa Barbara, Calif.) –– The discovery of nine new planets challenges the reigning theory of the formation of planets, according to new observations by astronomers. Two of the astronomers involved in the discoveries are based at the UC Santa Barbara-affiliated Las Cumbres Observatory Global Telescope Network (LCOGT), based in Goleta, Calif., near UCSB.


Unlike the planets in our solar system, two of the newly discovered planets are orbiting in the opposite direction to the rotation of their host star. This, along with a recent study of other exoplanets, upsets the primary theory of how planets are formed. There is a preponderance of these planets with their orbital spin going opposite to that of their parent star. They are called exoplanets because they are located outside of our solar system.


These and other related discoveries are being presented at the UK National Astronomy Meeting in Glasgow, Scotland, this week. This is the first public mention of the new planets and the research will be described in upcoming scientific journal articles.


"Planet evolution theorists now have to explain how so many planets came to be orbiting like this," said Tim Lister, a project scientist at LCOGT. Lister leads a major part of the observational campaigns along with Rachel Street of LCOGT, Andrew Cameron of the University of St. Andrews in Scotland, and Didier Queloz, of the Geneva Observatory in Switzerland.


Data from LCOGT was instrumental in confirming the new planet discoveries. By adding these nine new "transiting" planets, the number of known transiting planets has grown from 71 to 80. A transit occurs when a celestial body passes in front of its host star and blocks some of the star's light. This type of eclipse causes a small drop in the apparent brightness of the star and enables the planet's mass, diameter, density, and temperature to be deduced.


After the initial detection of the new exoplanets by the Wide Angle Search for Planets (WASP), the team of astronomers combined data from LCOGT's 2.0-meter Faulkes Telescopes in Hawaii and Australia with follow-up from other telescopes to confirm the discoveries and characterize the planets.


The planets are revolving around nearby stars in our galaxy within 1,000 light years of our sun. Their stars are located in the constellations Pegasus, Virgo, Pisces, and Andromeda in the northern hemisphere, and Eridanus, Hydra, Cetus, and Phoenix in the southern hemisphere.


The nine planets are called "Hot Jupiters." These planets are giant gas planets that orbit close to their star. In the 15 years since the first Hot Jupiters were discovered, their origin has been a puzzle. Because they are both large and close, they are easier to detect from their gravitational effect on their stars, and more likely to transit the disk of the star. Most of the first exoplanets discovered were of this type.


The cores of giant planets are thought to form from a mix of rock and ice particles found only in the cold outer reaches of planetary systems. Hot Jupiters, therefore, must form far from their star and subsequently migrate inwards over the course of a few million years. Many astronomers believed this could happen due to gravitational interactions with the disk of dust from which they formed, which might have also subsequently formed Earth-like rocky planets. However, these new results suggest that this may not be the whole story, because it does not explain how planets end up orbiting in a direction contrary that of the disk.


According to the research team, the best alternative migration theory suggests that the proximity of Hot Jupiters to their stars is not due to interactions with the dust disk at all, but to a slower evolution involving a gravitational tug-of-war with more distant planetary or stellar companions over hundreds of millions of years. Bounced onto a tilted and elongated orbit, a wandering gas giant would suffer tidal friction every time it swung close to the star, eventually becoming parked in a near circular, but randomly tilted orbit close to the star. "In this scenario, smaller planets in orbits similar to Earth's are unlikely to survive," said Rachel Street.

Las Cumbres Observatory Global Telescope Network is a non-profit organization dedicated to building a worldwide network of robotically controlled telescopes, which will enable astronomers to observe 24 hours a day, from both hemispheres. Currently, LCOGT operates two 2.0-meter telescopes: Faulkes North in Maui, Hawaii, and Faulkes South in New South Wales, Australia. LCOGT also has a telescope in Sedgwick Reserve, a nature reserve in Central California funded and managed by UC and UCSB. Over the course of the next few years, an armada of telescopes will be commissioned, distributed over six sites in both hemispheres of the globe, all controlled from LCOGT's headquarters in Goleta, Calif. These new facilities will be one of the largest networks of telescopes in the world, and will be an unprecedented tool for exploring the dynamic nature of a range of astrophysical phenomena. LCOGT's flexible approach to scheduling means the network provides responsive and highly efficient follow-up for large-scale surveys such as WASP. LCOGT is affiliated with neighboring UC Santa Barbara.
