Aldebaran is approximately 65 light years from Earth.

What is the difference between a constellation and a star?

A constellation is a group of stars that form a recognizable pattern in the sky, while a star is a celestial object that generates its own light and heat through nuclear fusion. Stars are individual bodies that can be part of a constellation or exist on their own.

How far is Ursa Major from the sun?

Any constellation is a group of stars that appear to form some kind of pattern,

but have no connection with each other. They all happen to be in roughly the

same direction from us, but they're all at different distances. So there's no

such thing as a constellation's distance from us.

Note that the Earth's distance from the sun is about 0.00000038 of the distance

from the sun to the next nearest star.

What is the history of the constellation cancer?

The Chaldeans first gave the name Cancer to this group of stars which they claimed represented a crab. They felt that a crab, which walks backwards, typifies the sun's motion when it is in this area of the zodiac. During this time. We refer to the 23.5 N latitude as the Tropic of Cancer as it marks the northernmost point at which the sun is directly overhead at noon. The Greeks refer to Cancer as being the crab sent by Hera to attack Hercules while he was battling the nine-headed monster Hydra. The little crab bit Hercules' toes and was crushed in the end. In honor of its bravery, Hera placed it in the sky. M44, the Beehive cluster in the center of Cancer has an interesting history in weather forecasting. Pliny the Elder wrote that "if Praesepe is not visible in a clear sky, it foretells the coming of a violent storm." This simply meant that a turbulent atmosphere makes seeing dim objects more difficult, and such an atmosphere often precedes a storm.

What constellation is mercury in?

The planet Mercury is located int he constellation Taurus, which is also known as the Bull. Mercury is the closest planet to the Sun.

What constellation is Saturn in?

Constellations are formed from the fixed stars. Saturn is a planet, not a fixed star - the word planet means wanderer. However, the planets travel through the constellations of the zodiac. Saturn is currently in the constellation Leo the Lion and will be for another year or so, until it moves into Virgo, the Harvest Maiden and will remain there for many years, since 1) Saturn moves so slowly and 2) Virgo is such a large constellation.

It should be remembered that the constellations are merely concocted images useful as "sky-marks" resulting from the chance relative positions of stars as seen from Earth. When we say a planet in our Solar System is "in" or "passing through" any particular constellation, it is simply moving across the line of sight. Physically, it is no-where near the constellation's own stars.

What is a primary star in a constellation called?

The primary star in a constellation is called the "Alpha" star - it's almost always the brightest one in the constellation. "Beta" is the second brightest, and it follows the Greek Alphabet as the stars get dimmer... Polaris is the North Star located in the constellation Ursa Minor - the Little Bear.

How much did southern Cross Station cost to complete?

Project Information
Details Project name
Southern Cross Station (formerly Spencer Street Station) Value
$309 million (Net Present Value June 2002) is the net cost to government. Status
Service Delivery Commenced Department or agency
Department of Infrastructure, Southern Cross Station Authority Private sector partner
Civic Nexus consortium, comprising the following partners:

-ABN Amro;
-Leighton Contractors;
-Daryl Jackson Architecture;
-Nicholas Grimshaw and Partners;
-Honeywell Limited; and
-Delaware North Australia. Description
Southern Cross Station (formerly known as Spencer Street Station) has been redeveloped into a world class station for Victoria. It is a gateway to Melbourne and the regions, and links the emerging Docklands precinct with the central business district of Melbourne.

The station project is managed on behalf of the Victorian Government by the Southern Cross Station Authority (SCSA) in partnership with the Civic Nexus Consortium.

The project includes two components:

  • the transport interchange redevelopment (for which the government has entered into a long-term service contract with Civic Nexus); and
  • a commercial redevelopment that includes a retail precinct, car parking and offices (these are commercial developments which involve no payment by the government).

Some of the features of the transport interchange include:

  • an open design light filled space with full glass frontage to Spencer Street and Collins Street with platform access from both the Bourke Street Bridge and Collins Street extension;
  • more passenger information screens with real time train arrival and departure information and comfortable waiting areas;
  • a 30-bay coach station;
  • secure, sheltered parking facilities for 800 cars and five-minute drop off and pick up area; and
  • improved public facilities and new retail outlets.

The project is a key initiative of the Victorian Government's $2 billion 'Revitalising Victorian Rail' program, which aims to improve passenger and freight rail service across Victoria.

The contract with Civic Nexus is to design, build, finance and maintain the transport interchange. The contract was executed on 2 July 2002 after a competitive tender process.

The Civic Nexus consortium, financed and led by ABN Amro Australia, contracted Leighton Contractors, Honeywell and Delaware North Australia to deliver and operate the development.

The Southern Cross Station Authority will manage the Partnerships Victoria contract for the transport interchange. There are a number of operators at the site who lease rail and station infrastructure to provide key rail services to the public. They are responsible for managing the rail infrastructure and platforms, including track, metro train control system and the electrical control system. These operators include Connex, V/Line Passenger and Freight Victoria.

Practical completion handover occurred with effect from July 2006. The other commercial and retail developments will continue over time.

In June 2007 the station was awarded the Royal Institute of British Architects (RIBA) Lubetkin Prize for the most outstanding building outside the European Union, and the RIBA International Award. The Station has also collected some Australian awards such as the Australian Construction Achievement Award 2007.
