Subway Party

Two small-town merchants were visiting New York City for the first time to attend a conference.

There was a large party thrown, with lots of food and drink. At the end of the party, they both staggered outside.

One guy crossed the street, while the other stumbled into a subway entrance.

When the 1st guy reached the other side of the street, he noticed the other emerging from the subway stairs.

"Where ya been?"

he slurred.

"I don't know," gushed the other guy, "but you should see the train set that guy has in his basement!"

First exoplanet announced in error

In 1991, a University of Manchester scientist announced the finding a planet outside of solar system. Andrew G. Lyne of the University of Manchester subsequently retracted his claim for a planet around pulsar PSR 1829-10 at the Jan 1992 meeting of the American Astronomical Society in Atlanta. He said that the modulation of radio waves coming from the pulsar was caused not by the presence of a planet but was in fact an artifact of the Earth's motion around the Sun. That possibility that had been considered but then discounted in earlier studies of the data. The first exoplanets (and were later confirmated) were announced in an article in Nature in 1992 by Aleksander Wolszczan and Dale Frail.
