Clear skies permitting, an extraordinary lunar eclipse will be visible from Wisconsin in the early morning hours of Tuesday, Dec. 21.
Until 2006, astronomers had not carefully defined “planet,” says James Lattis, director of the UW Space Place. Asteroids were not considered planets because they are too small and numerous. Likewise, comets were not considered planets because they are too small and have noncircular orbits that go far outside the plane of the solar system (location …
Courtesy European Space Agency (ESA/Hubble). Stars twinkle because we view them through our atmosphere, says James Lattis, director of University of Wisconsin-Madison Space Place. “Seen from the moon, where there is no atmosphere, stars do not twinkle at all, but here on Earth starlight passes through many miles of air on its way to our …
Saturn imaged by the Cassini Orbiter. Image: courtesy Jet Propulsion Lab Planetary ring systems are complicated, notes UW Space Place Director Jim Lattis, and they are more common than once believed. For ages, Saturn was thought to be the only planet in our solar system with a ring system. But in recent years ring systems …
Moments before bursting in a dazzling fireball over southwestern Wisconsin, a likely meteor appears as a bright dot in the Wednesday night sky. This image was captured around 10:07 p.m., April 14 by a camera mounted on the northwest corner of the Atmospheric and Oceanic Sciences Building on the University of Wisconsin-Madison campus. A dazzling …
For almost 50 years, astronomers have puzzled over the youthful appearance of stars known as blue stragglers.
On Oct. 13, 1959, University of Wisconsin-Madison professors Verner Suomi and Robert Parent crouched in a bunker at Cape Canaveral, sweating through the countdown for the Juno II rocket perched on its launching pad 150 yards away.
In the cosmos, all celestial objects – planets, stars, galaxies and clusters of galaxies – have magnetic fields. On Earth, the magnetic field of our home planet is most easily observed in a compass where the needle points north.
The Washburn Observatory, the University of Wisconsin-Madison’s gate to the heavens, will open later this month following a careful two-year renovation that preserved its hilltop charm and historic significance.
Space is probably infinite, but we can see only the part that contains stars or galaxies whose light has been able to reach us, says Francis Halzen, a professor of physics. The universe originated about 13.7 billion years ago with the Big Bang, so light cannot have been traveling for more than 13.7 billion years. …
“We don’t know,” says Ed Churchwell, professor of astronomy. “We know it’s a very large number.” It’s in the hundreds of billions, Churchwell says. In contrast, there are but 4 billion stars in our own galaxy, the Milky Way — and the number will keep growing for some time before we run out of galaxies …
On Saturday, June 27, wonders from the far reaches of the universe will be brought down to Earth on the Capitol Square.
The University of Wisconsin-Madison Space Place and the Monona Terrace invite the public to Planet Trek Fest at Monona Terrace on Saturday, June 20.
“Galileo Under Wisconsin Skies,” a series of special events presented by the University of Wisconsin-Madison Department of Astronomy July 19-22, will commemorate the 400th anniversary of Galileo’s telescope, the International Year of Astronomy and the renovation of Washburn Observatory at UW-Madison.
Dane County residents have a new way to appreciate the solar system, thanks to Planet Trek Dane County, which offers pedestrians and bikers a chance to discover the 11 biggest objects in the solar system at the correct scale of size and distance.
Few areas of science enchant us as much as astronomy. We view the stars each night; we make connections between astronomy and many other scientific fields. Rarely, though, do we get a chance to explore the heavens through organized events.
Arthur D. Code, whose lifelong love of the stars and the night sky led to a meteoric career in astrophysics, died in Madison, Wis., on March 11 after a long illness. He was 85.
As the 2008-09 Antarctic drilling season concludes, the IceCube Neutrino Observatory is on track to be finished as planned in 2011.
