Loud Train

A man had to attend a large convention in Chicago. On this particular trip he decided to bring his wife. When they arrived at their hotel and were shown to their room, the man said: "You rest here while I register - I'll be back within an hour."
The wife lies down on the bed... just then, an elevated train passes by very close to the window and shakes the room so hard she's thrown out of the bed. Thinking this must be a freak occurrence, she lies down once more. Again a train shakes the room so violently, she's pitched to the floor.
Exasperated, she calls the front desk, asks for the manager. The manager says he'll be right up. The manager (naturally) is sceptical but the wife insists the story is true.
"Look,... lie here on the bed - you'll be thrown right to the floor!"
So he lies down next to the wife... Just then the husband walks in. "What," he says, "are you doing here?"
The manager replies: "Would you believe I'm waiting for a train?"

Sodium atmosphere

In 2001, sodium was detected in the atmosphere of an extrasolar planet by the Hubble Space Telescope. The planetary atmosphere of HD 209458b was the first outside our solar system to be measured. The planet, informally known as Osiris, was the first transiting planet discovered (5 Nov 1999). It orbits the sun-like star designated HD 209458. Later measurements with the Hubble Space Telescope Imaging Spectrograph (2003-4), found an enormous ellipsoidal envelope of hydrogen, carbon and oxygen around the planet with a temperature that reaches 10,000°C, resulting in a significant "tail" of atoms moving at speeds greater than the escape velocity.«[Image: artist's visualization of the planet crossing in front of its sun-like star.]
