The 6th-Annual Utah Skies Star Party Series, co-sponsored with the Snyderville Basin Special Recreation District, continues tonight. Young and old can experience astronomy in a casual atmosphere under some of Park City’s darkest skies. The event takes place tonight!!! Saturday night July 29th from 8:30pm until 1:00am. We’ll have some nice views of the [...]

The orbiting Cassini Spacecraft has discovered what appear to be lakes on Saturn’s moon Titan. Scientists had speculated that they might find lakes of liquid methane in the moons colder northern regions, and recent data captured by Cassini seems to back this.

(NASA) This new false-colored image from NASA’s Hubble, Chandra and Spitzer space telescopes shows a giant jet of particles that has been shot out from the vicinity of a type of supermassive black hole called a quasar. The jet is enormous, stretching across more than 100,000 light-years of space . a size comparable to our [...]

The annual Delta Aquarid Meteor Shower peaks in the wee hours this coming Friday morning. Skywatchers under clear, dark skies can see as many as 10-15 meteors per hour. Checkout Spaceweather.com for more details.

A powerful solar eruption was recorded yesterday. The event triggered a Coronal Mass Ejection (CME) that, while not perfectly Earth-directed, will likely deliver a glancing blow this weekend. Skywatchers are encouraged to keep an eye on the northern horizon. Checkout Spaceweather.com for more details.

(NASA) - The STS-121 astronauts returned home today from a successful mission to the International Space Station when Space Shuttle Discovery touched down at Kennedy Space Center, Fla. Landing occurred at 9:14 a.m. EDT. Discovery gave the United States a birthday present when it launched July 4. STS-121 spent just under 13 days in orbit, [...]

NASA scientists have determined the formation of clouds is affected by the lightness or darkness of air pollution particles. This also impacts Earth’s climate. In a breakthrough study published Thursday in the online edition of Science, scientists explain why aerosols — tiny particles suspended in air pollution and smoke — sometimes stop clouds from forming [...]

When the sun is low in the sky, its light travels through much more atmosphere than when it’s overhead. Throught this long journey to our eyes, the shorter wavelengths of light (blues and greens) are scattered by particulate matter (aerosols) in the air (an effect known as Rayleigh scattering), yielding the reds and oranges of [...]

A large Coronal Mass Ejection (CME) erupted on the Sun Thursday afternoon. It is expected to sweep by Earth tonight… possibly triggering a display of the northern lights. Skywatchers (especially those at higher latitudes) are encouraged to keep an eye on the northern horizon. Checkout Spaceweather.com for more details.

Joint operations are under way for the STS-121 and Expedition 13 crews. The STS-121 astronauts arrived when Space Shuttle Discovery docked with the International Space Station this morning at 10:52 EDT. They were welcomed on to the station by Expedition 13 at 12:30 p.m. EDT. Discovery delivered supplies and equipment to the station. Also arriving [...]
