Meteors Are Coming! Get Away From The City!

Meteors are predicted! There going to be everywhere! Look up in the sky to see, but if you’re in the city you won’t see much. The light pollution from the city will obscure your view.

Get out in the country under clear dark skies to have the best views of the coming meteor showers.

Read the article in the San Francisco Chronicle about the upcoming meteor showers over this next month or so.

METEOR SHOWERS / For sky lights, put big city behind you

METEOR SHOWERS
For sky lights, put big city behind you

Thursday, July 23, 2009

The night time is the right time – right now – for a spectacular sky party.

All the key factors are synchronizing for a big show, where up to 100 shooting stars per hour are visible on many nights. Peak nights can be even better.

Over the next few weeks, three meteors showers will converge, with the best shows expected July 28-30 and Aug. 12-13. The timing is good because with few forest fires so far this year, skies are clear over most of Northern California, pristine in the high country. In addition, the viewing conditions look to be excellent in the next 10 days, with a new moon (dark) having arrived Tuesday; the next full moon won’t arrive until Aug. 5.

Meteor Fireball In Sweden

The Swedish are lucky people as they are witness to one of the most beautiful natural phenomena the natural world has known. A huge fireball streaked across the southwestern skies of Sweden early Saturday evening. Gothenburg (or Göteborg) SOS and air rescue service was inundated with reports of a fireball in the sky around 8pm Saturday Jan 17th.

Meteors typically burn up upon entry into Earth’s atmosphere, and there a chance this might be debris from a satellite. Either way you look at it it is certainly a spectacular event. The light show was fabulously bright and displayed an array of colors from bright blue streaks, a big blue-white flash, and a gorgeous red-orange and yellow tail.

What Is A Meteor?

What is a Meteor?

Information about Meteors, Meteoroids, Fireballs & Meteorites.

Meteors and “Shooting Stars”

Meteors are most often seen as a very brief streak of light in the night sky. They typically occur and disappear so quickly that you wonder if you actually saw them. These streaks of light are commonly called “shooting stars” or “falling stars”. Although they are most often seen at night, especially bright meteors can be seen during daylight. The photo at right shows a meteor in the sky over Quebec, Canada on an early November morning.

What are Meteoroids?

The streak that we call a meteor is a trail of glowing vapor produced when a small particle of space debris enters Earth’s atmosphere. These particles of space debris are collectively referred to as “meteoroids.” Millions of meteoroids enter earth’s atmosphere every day. They are believed to originate within our own solar system rather than from interstellar space. Most meteoroids that enter Earth’s atmosphere are tiny particles of comets, asteroids, Mars or Moon that travel through space and collide with Earth’s atmosphere.

Giant Meteor Fireball Explodes Over Northwest U.S.

Giant Meteor Fireball Explodes Over Northwest U.S.

Excerpt:

A meteor zipped across the U.S. Pacific Northwest sky early Tuesday morning before exploding, possibly littering eastern Oregon with marble- to basketball-size space rocks, an expert says.

Impact sites are yet to be found, according to Richard Pugh, a scientist with the Cascadia Meteorite Laboratory at Portland State University in Oregon.

Metallic rock that crashed into house in New Jersey photo

* Meteorite’s Organic Matter Older Than the Sun, Study Says (November 30, 2006)

* Meteorite Impact Reformulated Earth’s Crust, Study Shows (January 12, 2006)

* Virtual Solar System

January 5, 2007—It looks like a shiny lump of fool’s gold, and it certainly has authorities fooled as to just what it is.

This metallic rocklike object crashed through the roof of a New Jersey home on January 2, ripping through the ceiling and ricocheting off a tiled bathroom floor before lodging in a wall.

No one was hurt by the impact, but local detectives trying to identify the mysterious debris may have their professional egos a little bruised.

“I’ve never seen anything like it in my career,” Lt. Robert Brightman of the Freehold Township Police Department told the Associated Press at a press conference yesterday.

Experts from the U.S. Federal Aviation Administration have already inspected the 13-ounce (0.4 kilogram) lump and determined that it is not a stray airplane part.

Another test found that the object is not radioactive, although it does appear to be magnetic.

Some astronomers have speculated that that the object could be a meteorite, since the Quadrantid meteor shower occurs annually in early January.

But meteor showers typically involve small particles of icy rock, not big metal chunks, so if the mass is a meteorite, it’s likely an unusual one.

Other theories have suggested that the lump is a tool lost by an astronaut or flotsam from an orbiting satellite that melted as it entered Earth’s atmosphere.

Brightman said scientists are currently testing the object and hope to have results by the end of the week.

Meteoroid

An article on the difference between meteors, meteoroids, meteorites, fireballs, bolides tektites, meteoric dust, formation, asteroids, and orbits.

Excerpt:

“…A meteoroid is a small sand- to boulder-sized particle of debris in the Solar System. The visible path of a meteoroid that enters Earth’s (or another body’s) atmosphere is called a meteor, or commonly a “shooting star” or “falling star”. If a meteoroid reaches the ground, it is then called a meteorite…” SOURCE – Meteoroids
