Scientists recover meteorites from asteroid which entered our atmosphere

This endeavour was the first of its kind- trying to observe an asteroid entering the atmosphere and recovering parts of the celestial body in the form of meteorites. Recently it was known that a very small asteroid was about to enter the atmosphere and burn up on 10/7/2008. The hope was that the asteroid could be observed entering the atmosphere and that some meteorites would survive on reentry.
Here is more information and a photo of one of the bigger meteorites

Sungrazer Comet photo 3/21/2009

This photo was snapped on 12/23/1996 by the LASCO oriented SOHO space telescope and showed a comet arching into and later being destroyed by the Sun’s heat.

Small asteroid flies close by Earth

On 3/20/2009, asteroid 2009 DO111 flew past Earth only about 288,000 miles away--just beyond the orbit of the Moon! About the size of a football field, this dangerous space rock was visible in backyard telescopes as it sped through the constellation Cassiopeia shining at 13th magnitude, far below naked eye visibility.

Here is a nice photo taken

Interaction with bird migrations and learn more

There is a great website that bird lovers might not know about. It is called Journey North and has many details about migrations for hummingbirds and many other birds. It is well done so check it out . And while you are at it check out the other interactive websites
I coordinated and wrote the Annenburg website about weather and created the stormchaser simulation.

Hummingbirds Journey North

This is a neat website that provides ongoing information concerning migration patterns about birds, monarch butterflies and more. Here is one of my favorite about my favorite birds, hummingbirds. Here is a sample of the email reports that I get. (You, teachers and students can sign up to input your data and more).

* Explore: Is Your Schoolyard Ready for Hummingbirds?
* Questions? "Ask the Expert" Opens March 13
* This Week's Hummingbird Resources

*****************************************************************
Highlights: Welcoming the Waves!
"Our little jewels are back," writes one observer. Warm southerly winds paved the way this week for a flood of ruby-throated hummingbirds: 66 new reports! Can you find the two new states they've moved into? How does this compare with your predictions -- or with last year's migration? (Look at today's Rubythroat Map Questions handout.)

Out West, a big batch of rufous hummingbirds are gathered in Oregon and Washington. A careful observer has one explanation: "The red-flowering currant (one of their earliest spring food sources) is just about to open its first flowers." They may be feeding on blooming wildflowers, but how did they manage to get so far ahead of the rubythroats? Today's slideshow will give you some clues.

"I saw my first male. He comes every year. Females follow," writes one hummingbird lover. So far, most observers have spotted only male birds of both species. What do you think is going on? Explore!

It looks like it will be a colder, rainy weekend in rubythroat country. Will they rush northward ahead of the front or just hunker down? Keep your eyes peeled and stay tuned for next week's update! In the meantime, what can you learn about this incredible migration from other Journey north observers?

*****************************************************************
Journal and Slideshow: Why Are Rufous Hummingbirds Far Ahead?
Look at both of this week's migration maps, above. How can rufous hummingbirds be in Canada already, when rubythroats are still gathered in the southern United States? Are the Rufous hummers faster or more eager? Is this just an unusual year? How would you explain this?

Think: First, write your ideas on the Hummingbird Journal page. Then compare migrations by watching the slideshow.

*****************************************************************
Explore: Is Your Schoolyard Ready for Hummingbirds?
Hungry hummingbirds are headed your way! Even if you live in an area where they don't nest, some might stop by on their way north. Will they be able to find what they need to survive in your backyard or schoolyard? Let's explore!

Questions? Ask the Expert Opens March 13
Journey North's hummingbird expert (and bander) Lanny Chambers has again volunteered to answer your questions. Lanny has had a life-long passion for hummingbirds. He researches them and runs an award-winning Web site about their migrations. Here is your chance to ask Lanny questions you haven't been able to answer yourselves.

The deadline for questions is Friday, March 27 (1 p.m. EDT).

* Meet Lanny and submit your questions on the Web.

Comet Lulin still looking good

I've posted my photos previously of the comet. Some other amateaurs still have some nice photos. Here's another one.

Comparing Jupiter’s Moon Europe to our Moon

Is there life under the ice of Europe? This premise and the observations and characteristics for Europa are tentalizing. Ice covered, there are cracks with orange-red coloration with the cracks. Is there seas under the ice? Other areas on Earth have life in inhospitable conditions? Maybe on Europe too?

A mission to Europa is being planned that would arrive at Europa in 2020. So it is a long way off and so is paying for the billions of dollars for this mission. But for now we can learn more about Europa and its tentalizing features at

Beautiful planet Saturn- jewel of the Solar System

Saturn is not the brightest planet as seen from the Earth but it sure is the most beautiful. It’s rings, observed by using a small or larger telescope, always amazes everyone and is a wonder to behold. Once thought to be the only planet with rings (we now know Jupiter, Uranus and even Neptune have smaller rings), these rings have most likely been caused by pieces from other moons and shattered moons and materials. More about the rings and Saturn.

Iceball falls into the Sun

On Feb. 23rd, the Solar and Heliospheric Observatory (SOHO) observed a comet plunge into the sun and disintegrate. This one was part of a family of small comets called Kreutz sungrazers which resulted from the breakup of a giant comet s over 2000 years ago. Most are small and faint, but this one was a beauty. Watch the movie of its demise. The comet appears coming up from the left at around 8 oclock. (The black disc is a coronography type instruments that shield the Sun to show the surrounding area).

Green Comet and Blue Star Regulus

Last night February 28, at Powell Observatory, 20 minutes south of Kansas City, we welcomed w about 200 people who wanted to observe the comet through our 30 inch telescope. The snow had stopped, the clouds disappeared and we had color clear weather. The green comet was glowing at 6th magnitude. It now was up and south of the bright star Regulus. People could see its coma (cloud like area around the comet head called the nucleus , which you can't see in this photo) and nucleus which was near the center but was more difficult to observe. (Photo taken by Eric Flescher through 6 inch telescope,60 seconds- I am workin on the color photo).
Another person in Italy took a picture of the green comet when it was near bluish Spica a few days ago (we had clouds during this close approach). You can see it at

On 2/25/2009, I took more photos of the comet. The tail is now easily seen and more pronounced as it has swung around Earth and now away from it, heading toward the outer reaches of the solar system. The tail is out to the side instead of behind the coma so we can now see it. Now the view is more like what we normally think of a comet, with it's nucleus having a streaming tail (boiling off by the Sun's energy), pointing away from the Sun.
