Mars changed from a warm planet into a colder one, now some news

Long ago, something bad happened to Mars, transforming a warm and hospitable world into the cold, seemingly lifeless desert we view today. Many scientists believe the Red Planet lost most of its atmospher. A new NASA mission named MAVEN is specifically designed to answer some questions about the series of events.

Surprising small asteroid hits

The asteroid "hit" took astronomers completely by surprise with
50 kton of TNT (two to three times more powerful than World War II-era atomic bombs). Apparently there was little news of it spread around the world for some reason (I only heard about it briefly) when it hit in Indonesia in the atmosphere.
See the smoke trail of the blast and a new video too by using links!

Crab Nebula further revealed

This supernova (exploding star) was so bright in 1054 that the Chinese recorded that it happened. Today we have different views of this phenomenon.

Mysterious trails from above are Martian Dustdevils trails

Dustdevils are found on Earth rising from the surface. However on Mars they are taller sometimes rising to 8 km (do you know how many miles this is?) into the thin Martian air. Read more

vast, glowing ribbon at the edge of the solar system

NASA's IBEX spacecraft has discovered a vast, glowing ribbon at the edge of the solar system. One mission scientist calls the discovery "shocking" and says theorists are "working like crazy" to explain the finding.

For planetarium programs, one of the best free ones find more at
Cartes du Ciel.
Hallo Northern Sky,
Celestia, and

Perseids what a hype and what a bust

I've been watching meteors for years so I guess when the skies are clear, whether cold or warm, I will try, as I have done over the years despite the hype. The hype of the Perseid meteor shower, this year , was nerve racking.

It was clear over Kansas for the most part but the Moon was keeping many of the faint ones. I don't care about seeing the faint ones, all I look forward is a few bright ones to remember.
I only could compare this Perseid hype to Comet Kohoutek when much is expected but little if nothing is delivered. Not only were two maximum dates expected but the extra bombardment was supposed to happen either later evening and/or early morning. This was compounded by observers seeing a lot (which led me to believe what are they smoking anyway) or literally nothing (my case).
A human eye can see so much and when the hype media says 100- 200 meteors per hour these are expectations not realizations. You are not going to go out and see fireballs falling around you. If you are lucky you can see one or two bring ones or some every few minutes at the peak.
I gave it a go one more time.
In Olathe, KS (near Kansas City), the Moon was finally setting a little lower so that the sky was darker in the area of the NE and the constellatioin Perseus. It was far better than last years Full Moon but up until now seeing the meteors was still disconcerting. However supposedly there was to be another "spike". So instead of going to bed, I go out my sleeping bag and waited, again.

In an hour , with clear skies, all I saw was 8 Perseids. But all except one was pretty bright.
The best was a short yellow Perseid at zero magnitude (not quite a fireball) , that left a nice 0.75 train (smoke trail). There were 2 fireballs (yellow and yellow-white) at -2 that were 25 degrees long and pretty. So at least I saw something.

But an all sky camera can see much more over time. Ths spectacular photo shows dozens. There is on that stands out and I wish the author would have said more how bright this particular wide bright one was.

Beautiful celestial structure: Pillars of Eagle Castle

This now famous part of the sky , seen with Hubble Space Telescope or not, is an amazingly rich photo of colors and celestial structures. The Eagle nebula comsic structions are both beautiful have a lot of curiousity that cries out to ask “what are these things?”

Bizarre mysterious lines on Saturn's moon Enceladus

Scientists still have many questions about how these structures called Tiger Stripes on Saturn's Enceladus form and then loft jets of ice particles into the space around the moon and creating one of the rings of Saturn. This photo from the Cassini spacecraft shows much detail.

Mars will not look as big "as a saucer " this August


Here it comes again. The planet Mars will be close but it will NOT appear as "big as the Moon" so some people and naysayers say.
This cartoon was just in the newspaper concerning this.
