  • Photo: Messier 82 Letting off steam: Gas discharge terminates galaxy’s star formation Dec. 3, 2014 With the help of a radio telescope in the French Alps, an international team of astronomers, including two from the University of Wisconsin-Madison, has observed a never-before-seen stage of galactic evolution. Writing in this week’s Nature, a group that includes UW-Madison astronomers Aleks Diamond-Stanic and Christy Tremonti, reports measurements of dense, cold hydrogen gas being blasted from a distant star-forming galaxy, the first direct observation of the “blow out” phase of a galaxy’s evolution.
  • Photo: Astronaut Reid Wiseman injects a fixative solution onto the seedlings. UW team’s plants return to Earth after growing in space Nov. 6, 2014 Researchers at Simon Gilroy's lab in the Department of Botany at the University of Wisconsin-Madison expect to greet a truck this afternoon that is carrying small containers holding more than 1,000 frozen plants that germinated and grew aboard the International Space Station.
  • New Milky Way portrait to be on Town Center media wall March 20, 2014 The dramatic new infrared picture of the plane of our galaxy will be viewable for the next week on the large media wall in the Town Center of the Wisconsin Institutes for Discovery on the UW-Madison campus.
  • Milky Way portrait Dramatic new portrait helps define Milky Way’s shape, contents March 20, 2014 Using more than 2 million images collected by NASA’s orbiting Spitzer Space Telescope, a team of Wisconsin scientists has stitched together a dramatic 360-degree portrait of the Milky Way, providing new details of our galaxy’s structure and contents.
  • Fledgling supernova remnant reveals neutron star's secrets Dec. 4, 2013 With the help of NASA’s Chandra X-ray Observatory and the Australia Telescope Compact Array, an international team of astronomers has identified the glowing wreck of a star that exploded a mere 2,500 years ago — the blink of an eye in astronomical terms.
  • IceCube pushes neutrinos to the forefront of astronomy Nov. 21, 2013 The IceCube Neutrino Observatory, a particle detector buried in the Antarctic ice, is a demonstration of the power of the human passion for discovery, where scientific ingenuity meets technological innovation.
  • IceCube feature film to premiere in Milwaukee planetarium show Oct. 31, 2013 The IceCube Neutrino Observatory is one of a kind. Built deep within the Antarctic ice, it is the world’s largest neutrino detector. Now, thanks to a collaboration between the Wisconsin IceCube Particle Astrophysics Center (WIPAC) and the Milwaukee Public Museum, it boasts another unique aspect: its own planetarium show.
  • The sun also flips: 11-year solar cycle wimpy, but peaking Oct. 16, 2013 In a 3-meter diameter hollow aluminum sphere, Cary Forest, a University of Wisconsin-Madison physics professor, is stirring and heating plasmas to 500,000 degrees Fahrenheit to experimentally mimic the magnetic field-inducing cosmic dynamos at the heart of planets, stars and other celestial bodies.
  • Photo:reflection nebula IC 63 in the constellation Cassiopeia Observations reveal critical interplay of interstellar dust, hydrogen Sept. 25, 2013 For astrophysicists, the interplay of hydrogen - the most common molecule in the universe - and the vast clouds of dust that fill the voids of interstellar space has been an intractable puzzle of stellar evolution.
  • Photo: Epic UW brings outreach to Epic's 'Deep Space' Sept. 19, 2013 Hosting a series of exhibits on Epic Systems campus in Verona for the health care software company’s massive annual users’ group meeting, UW-Madison researchers and outreach experts focused on “Deep Space,” the name of Epic’s new underground auditorium, as a common theme to demonstrate how campus research is making an impact in and out of this world.
  • Images of Saturn Massive storm pulls water and ammonia ices from Saturn’s depths Sept. 3, 2013 Now, thanks to near-infrared spectral measurements taken by NASA’s Cassini orbiter and analysis of near-infrared color signatures by researchers at UW-Madison, Saturn’s superstorm is helping scientists flesh out a picture of the composition of the planet’s atmosphere at depths typically obscured by a thick high-altitude haze.
  • With Ceres back in orbit, Planet Trek blasts off for the bike season June 10, 2013 The Rodney Dangerfield of celestial bodies is back.
  • International astrophysics reaches Milwaukee April 16, 2013 Trips to the South Pole usually require a lot of specialized equipment, but Nils Irland's packing list for his November 2012 visit included some items unusual even by those standards: a specially designed video camera, extra batteries, and lots and lots of data storage.
  • Puzzle of how spiral galaxies get their arms comes into focus April 2, 2013 Despite their common morphology, how galaxies like ours get and maintain their characteristic arms has proved to be an enduring puzzle in astrophysics. How do the arms of spiral galaxies arise? Do they change or come and go over time?
  • Photo: People looking at telescopes Universe in the Park takes astronomy to Wisconsin state parks Sept. 12, 2012 "I want to blow your mind, take you places you have never seen before. Do not hesitate to ask question. I will not bite."
  • Transit of Venus a rare event June 1, 2012 On the evening of Tuesday, June 5, the planet Venus will cross the disk of the Sun in what astronomers call a "transit."
  • Man working on telescope Washburn telescope optics get 130-year checkup, cleaning May 10, 2012 Bit by bit over the last two decades, the University of Wisconsin-Madison's iconic Washburn Observatory has been restored to its original sheen.
  • Illustration: Blue straggler Astronomers discover how mysterious blue straggler stars stay young Oct. 19, 2011 Mysterious "blue stragglers" are old stars that appear younger than they should be: they burn hot and blue. Several theories have attempted to explain why they don't show their age, but, until now, scientists have lacked the crucial observations with which to test each hypothesis.
  • Hubble image of the Eagle Nebula Clocking the mosh pit of interstellar space Oct. 5, 2011 The space between the stars in the Milky Way and all other galaxies is full of dust and gas, the raw materials from which stars and planets are made.
  • Photo: Sheinis Astronomy technique could help assess deadly melanomas April 26, 2011 As a young graduate student with a passion for surfing, Andy Sheinis soaked up a lot of California sun.
