FAU Astronomical Observatory -- Front Page

Welcome to the Observatory's Front Page. Included here are some of the latest news and articles that may be of interest to our visitors. General observatory information, such as location and maps, viewing schedules, Events Calendar, contact information, student class credits, parking and other general information, can be found on the "About the Observatory" page.

We also have a growing coverage about the issue of light pollution, what it is, what it does to the environment, to ourselves, to our wallets and resources, to our security and safety, to the majestic wonders of the night sky and what YOU can do about it. This is a man made problem that is prepetuated by a lack of awareness and is something that we all can correct.

What's Up in the Sky

 

Section updated: Mar. 30th, 2015.

The Sun currently appears in the constellation Pisces' realm. Gets passed by Mercury on Apr. the 10th and enters Aries the ram on Apr. 19th. It then enters Taurus's the bull's realm on the 15th of May. Passing by Mars on June the 4th and entering Gemini on June 22nd.

Solar System Planets:

Mercury currently appears in the morning in the constellation of Pisecs, will briefly passing through Cetus on April 3rd, before returning back into Pisces as it approaches the Sun for a superior conjunction on Apr. 10th. After then, look for it to appear in the evening skies.

Venus is in the boundaries of Ares the ram and will appear with Taurus the bull by April 7th. She'll appear just under 2.5° away from Messier 45, the Pleiades on April 11th. Then she'll continue on into Gemini on May the 8th, then appearing just over 1.5° away from the open cluster Messier 35.

Mars is in Ares the ram, and appears ever dimmer as he occupys the far side of the solar system from us. Mercury will appear to buzz by him on April 22nd. The old warrior will enter Taurus on May 3rd and then the Sun itself will pass him during their conjunction on June 14th. Afterwards, expect to see him on the flip side of the night in the eastern morning hours.

Jupiter, rising around 1510 EDT, is still retrograding in Cancer and will continue to do so until Apr. 8th when he becomes stationary and resumes prograde motion. Jupiter will reenter Leo on June the 8th and on June the 20th will appear in a nice triangle with a cresent Moon and Venus. On June the 30th look for Jupiter and Venus to appear about 1/3° apart from each other! A sight that is not to be missed!

Saturn currently rises just after midnight, with a brightness at mv = 0.44. It currently appears near ν Scorpii before dawn in the eastern skies. appearing almost as if part of the archinid's head stars. It started its retrograde on March 14th so we are on our way to its opposition on May the 23rd. It will enter Libra on May the 2th.

Uranus is slowly advancing through Pisces. Uranus will appear with the fish until Apr. 28th, 2018! Its opposition will occur on Oct. 12th.

Neptune is currently just under 2° north and east of Sigma Aquarii in the morning skies. It will get as close as 2° to λ Aquarii when it starts its retrograde, reaching opposition on Sept. 1st. It will reside in Aquarius until 2022.


Can You Identify This Image?

The image at the right shows locations of:

  1. southeast U.S. cities seen at night from space.
  2. inefficiently used energy resources and tax dollars continuously squandered by local city planners.
  3. local populations who are losing their humbling sense of wonder and awe of the night sky's majesty.
  4. increased, widespread disruptions to the local natural environment.
  5. projected increases of health problems in the local populations.
  6. all of the above.
