Space In General

I think I just saw my first comet/meteorite or whatever they are called on the way back from work 👍

Cool 👍 I remember the first time I saw a meteor - I was stargazing with my cousin and we both saw the same one. We were both gobsmacked, and stayed out for a couple of hours to see if we could see any more - we ended up seeing several that night. If you look at the sky for long enough on any clear night, you are likely to see at least one meteor, but you can often see many more, even on days when there is no increased chance of seeing them, such as annual meteor showers.
 
I saw my first meteor during a short car journey home one night about 12 years ago. Happened to look out the window at the right patch of sky a few seconds before it appeared.

Haven't seen many since then apart from the Perseids. Only ever spotted one or two that were brighter.
 
My first meteor was about 12 years ago as well but there was no way you could miss it (them) Looked like giant fireballs dragging across the sky on a clear night. Needless to say I was amazed but it is the only time I've ever seen anything like since.

It would probably destroy your garden in the process.

Just a small one, I don't need a crater. :lol:


Have any of you ever see one break through the clouds? That is so cool to see. I was waiting for a big thump but nothing.

Generally they burn up long before they get that low, it's not impossible (or unusual) for smaller fragments/remnants to make their way to the ground.

Also, to be visible coming through the cloud base at several hundred miles an hour it would have to be comparatively large, so the videos of the Russian meteor are the only ones your likely to see of that ilk!

Check out the footage of the meteor being retrieved from the lake if you can find it, incredible :D
 
That's why I was waiting for the sound, a sonic boom or something. But noooooo...

The Chelyabinsk meteor exploded at high altitude, between 100 000 and 76 000 feet. The fragments that reached the ground did so in dark flight, so if there had been a cloud layer they wouldn't have been visible when they passed through it.

Also, that explosion was estimated to be the size of roughly 20 - 30 Hiroshima bombs, so if you're ever unfortunate enough to see a glowing meteor pass through the cloud base it might just be the last thing you'll ever see.
 
The chances are very slim for seeing one. In fact, last year, scientists were on the lookout for 2013 TV135, which was (at that time) the most likely to hit Earth -- on April 13th 2036 -- with a chance of 0.0021% (1:48000). But even though it's such a small chance, once -- and if -- it happens, it might be very catastrophical, indeed.

And, not the most space related thing, but is anybody here going to watch 'Live From Space'?
 
@Dean, maybe.

Space really fascinates me. Not to the extent of becoming an astronaut... just star gazing. Laying back, with a friend and look up. You can get really poetic just looking up into the sky.

Yes, I was actually referring to the meteorite, not the original body. You're quite right of course that to see a meteorite at night it would have to be glowing...which it wouldn't be as it passed through the altitude of most normal cloud bases as there would no longer be sufficient ram pressure.

@Dean remember that Chelyabinsk wasn't actually the near-pass that people were expecting that day, it was the other asteroid that was expected to arrive first. You wait all that time for an asteroid etc. etc. :)
 
I watched it last night and enjoyed it. I will probably watch it again tonight and see the extras that are included during the Nat Geo showing.
 
This is one of those times I wished I had cable TV.
 
I find the space mirror really interesting. We go on expeditions to explore space, but what we discover is the Earth.

Here's a nice quote:

One morning I woke up and decided to look out the window to see where we were. We were flying over America and suddenly I saw snow, the first snow we ever saw from orbit. Light and powdery, it blended with the contours of the land, with the veins of the rivers. I thought autumn, snow... people are busy getting ready for winter. A few minutes later we were flying over the Atlantic, then Europe, and then Russia. I have never visited America, but I imagined that the arrival of autumn and winter is the same there as in other places, and the process of getting ready for them is the same. And then it struck me that we are all children of our Earth. It does not matter what country you look at. We are all Earth’s children, and we should treat her as our mother.

Soyuz T-9 mission, 1983)

There are no passengers on Starship Earth, only crew.

I heard that quote as a kid and thought it was horribly leftist tosh. Now... now I'm an old hippy I guess. Got a great collection of music though, so it worked out okay :D

2 moons of Saturn, Titan and Rhea captured by Cassini. I love space.

Rings are not terribly well understood, except that they appear on Saturn, and to a much lesser extent, on Jupiter, Uranus and Neptune. And moons are thought to be necessary for them to form. Rings are also thought to be primordial material, and to eventually resolve into moons. Saturn would appear it might be less primordial than the others, since its rings haven't resolved. So what is a supposedly primordial object, a centaur, doing with vibrant rings?? Quite possibly, it's not primordial.
 
The following article contains several NASA photographs of light emanating outward from the surface of Mars a short distance from the rover vehicle.

Currently, there is no official explanation from NASA.

Before leaping to the conclusion that the light is artificial and comes from an underground civilization, recall that scientists have recently affirmed similar lights on Earth originating prior to and during earthquake events. In brief, it is explained that pressures within rock formations cause charge separation and ionization which result in glowing particles releasing into the atmosphere.
 
It's a cosmic ray strike on one of the detectors... there are two imagers (left and right) that operate at the same time, but the "light" is only visible in one and not the other.

In my old job, we often used to detect cosmic rays hitting our camera from time to time.
