Washburn Observatory open Monday for public viewing of Mercury crossing sun

May 5, 2016

Weather permitting, Washburn Observatory will be open to the public for safe viewing of the event. Read More

High Throughput Computing helps LIGO confirm Einstein’s last unproven theory

March 8, 2016

A software program pioneered at UW–Madison churned away in the background, helping analyze data from billions of particle collisions. Read More

After long hiatus, Washburn Observatory public viewing to resume

February 26, 2016

The observatory had closed unexpectedly in April 2014 when a motor and gear box that operate a sliding door on the dome malfunctioned. Read More

UW astronomer recognized for demystifying star system

January 15, 2016

Sebastian Heinz has been honored by the American Astronomical Society for his work to unravel the mystery of Circinus X-1, a bizarre binary star system in our galaxy that exploded some 2,500 years ago. Read More

Clouds, like blankets, trap heat and are melting the Greenland Ice Sheet

January 12, 2016

A new study shows clouds are playing a larger role in heating the Greenland Ice Sheet than scientists previously believed, raising its temperature by 2 to 3 degrees compared to cloudless skies. Read More

Study questions dates for cataclysms on early moon, Earth

October 16, 2015

Phenomenally durable crystals called zircons are used to date some of the earliest and most dramatic cataclysms of the solar system. One is the super-duty collision that ejected material from Earth to form the moon roughly 50 million years after Earth formed. Another is the late heavy bombardment, a wave of impacts that may have created hellish surface conditions on the young Earth, about 4 billion years ago. Read More

Ancient rocks record first evidence for photosynthesis that made oxygen

October 5, 2015

A new study shows that iron-bearing rocks that formed at the ocean floor 3.2 billion years ago carry unmistakable evidence of oxygen. The only logical source for that oxygen is the earliest known example of photosynthesis by living organisms, say University of Wisconsin–Madison geoscientists. Read More

Recent sightings: Moon over Madison

September 28, 2015

Seen from the roof of Memorial Library, a supermoon rises in the nighttime sky behind the Wisconsin statue headdress atop the dome of the Wisconsin State Capitol building on Sept. 27, 2015. Read More

Balzan Prize goes to UW neutrino pioneer

September 16, 2015

Francis Halzen, the University of Wisconsin–Madison physicist and leader of the giant neutrino telescope known as IceCube, has been named winner of a 2015 Balzan Prize. Read More

New data from Antarctic detector firms up cosmic neutrino sighting

August 20, 2015

Researchers using the IceCube Neutrino Observatory have sorted through the billions of subatomic particles that zip through its frozen cubic-kilometer-sized detector each year to gather powerful new evidence in support of 2013 observations confirming the existence of cosmic neutrinos. Read More

Novel Morgridge technology may illuminate mystery moon caves

August 14, 2015

It's widely believed that the moon features networks of caves created when violent lava flows tore under the surface from ancient volcanoes. Some craters may actually be "skylights" where cave ceilings have crumbled. Read More

Neutron star’s echoes give astronomers a new measuring stick

June 23, 2015

In late 2013, when the neutron star at the heart of one of our galaxy’s oddest supernovae gave off a massive burst of X-rays, the resulting echoes — created when the X-rays bounced off clouds of dust in interstellar space — yielded a surprising new measuring stick for astronomers. Read More

Dark energy to be topic of Space Place event

May 26, 2015

"To Infinity and Beyond: The Accelerating Universe," a live broadcast from the World Science Festival about dark energy, an antigravitational force that confounds the conventional laws of physics, will be hosted on the evening of May 28 by UW–Madison's Space Place. Read More

Wisconsin contributions helped Hubble Space Telescope soar

April 21, 2015

It was “the flea on the tail of the dog.” Roughly 30 years ago, that was how University of Wisconsin–Madison astronomy Professor Robert C. Bless described the High Speed Photometer (HSP), a detector then under development at UW–Madison for the soon-to-be-launched Hubble Space Telescope. Read More

Hubble Space Telescope to star at April 14 Space Place event

April 9, 2015

Twenty-five years of spectacular imagery and groundbreaking astronomy from the Hubble Space Telescope will be the subject of a Tuesday, April 14 public presentation at UW–Madison’s Space Place. Read More

Automation offers big solution to big data in astronomy

March 24, 2015

It’s almost a rite of passage in physics and astronomy. Scientists spend years scrounging up money to build a fantastic new instrument. Then, when the long-awaited device finally approaches completion, the panic begins: How will they handle the torrent of data? Read More
