Constellation maps divide the celestial sphere into 88 parts, known as constellations, helping astronomers locate stars and deep sky objects. The star constellations that can be seen in the night sky depend on the observer’s location and season, and they change throughout the year. Out of the 88 constellations recognized by the International …

Observers can never see all 88 constellations from a single location on Earth. While some of the southern constellations can be seen from northern latitudes at certain times of year – Scorpius, for instance, is visible over the southern horizon in the summer – others never rise over the horizon.

Can you see the southern constellations from northern latitudes?

While some of the southern constellations can be seen from northern latitudes at certain times of year – Scorpius, for instance, is visible over the southern horizon in the summer – others never rise over the horizon.

ENTERING THE OBSERVATORY

To the western side of the Observatory is a large tree that you can climb.

ROOFTOP NOTES

After infiltrating the observatory grounds, climb up to the roof of the observatory. There is no simple stealth method here, so just cause a ruckus and eliminate all the redcoats on the roof.

OPEN TOWER NOTES

On the opposite side of the roof is an open tower with only TWO enemies. Cut down both baddies and then take the notes on the table.

COURTYARD NOTES

The final set of notes are in the courtyard. Make your way to ground level and sneak around the courtyard behind the redcoats. No need to kill the redcoats, so just quietly steal the pages and then exit the observatory via the large tree on the west side.

How many constellations can you see from a single location?

Observers can never see all 88 constellations from a single location on Earth. While some of the southern constellations can be seen from northern latitudes at certain times of year – Scorpius, for instance, is visible over the southern horizon in the summer – others never rise over the horizon. Crux, also known as the Southern Cross, which is prominent enough in the southern sky to be featured on several national flags in the southern hemisphere, can never be seen from most locations north of the equator. Similarly, the constellation Ursa Minor, which contains Polaris, the closest bright star to the north celestial pole, cannot be seen from most places south of the equator.

Why do we see different constellations at different times of the year?

As the Earth orbits around the Sun, constellations move slowly to the west over the course of a year and we see different parts of the sky at night because, as the seasons change, we are looking in a different direction in space. This means that different constellations are viewable at different times of year.

Which constellation is closest to the north pole?

Similarly, the constellation Ursa Minor, which contains Polaris, the closest bright star to the north celestial pole, cannot be seen from most places south of the equator.

Where are circumpolar stars located?

Near the equator, there are no circumpolar stars. With the celestial poles on the horizon, all stars appear to rise in the east and set in the west for observers at the equator. Observers can never see all 88 constellations from a single location on Earth.

Do stars move farther from the celestial poles?

Polaris and other stars lying near the celestial poles appear to move across a smaller area than stars lying closer to the equator. The farther they are from the poles, the wider the circle the stars make across the night sky. The stars that are close to the poles never set below the horizon for observers in locations where the stars are visible: they are circumpolar. Near the equator, there are no circumpolar stars. With the celestial poles on the horizon, all stars appear to rise in the east and set in the west for observers at the equator.

What is the spectral type of Sirius A?

It has 316% of the Sun’s abundance of iron. The star’s spectral type, A0mA1 Va , indicates that Sirius A would have the classification A1 based on its hydrogen and helium lines, but it would belong to the spectral class A0 based on the absorption lines of metals. The high content of metals is believed to be mainly present in the surface layers, not in the entire star.

What is the brightest star in the sky?

Sirius, Alpha Canis Majoris (α CMa), is the brightest star in the night sky and one of the nearest star systems to Earth. It has an apparent magnitude of -1.46 and lies at a distance of only 8.6 light years from the Sun. It is also known as the Dog Star, in reference to its position as the luminary of the constellation Canis Major, the Greater Dog.

How far apart are Sirius A and B?

Sirius A and Sirius B orbit each other every 50 years at a distance between 8.2 and 31.5 astronomical units, which translates into an angular separation between 3 and 11 arcseconds. At periastron (the closest approach), the two stars can only be resolved in a 12-inch or larger telescope. As they have been moving away from each other since the last periastron in 1994, Sirius A and Sirius B are easier to resolve. The average separation between the two stars is about 20 astronomical units, which is roughly equal to the distance between the Sun and Uranus. The stars will be farthest apart in 2019 and will come to the closest approach again in 2044.

Why is Sirius so bright?

Sirius appears so bright both because it is intrinsically luminous, with an energy output about 25.4 times that of the Sun, and because of its proximity to the solar system.

What is Sirius A?

Sirius is a binary star system composed of Sirius A, a white main sequence star with the spectral classification A0mA1 Va, and Sirius B, a white dwarf of the spectral type DA2. Nicknamed The Pup, Sirius B is the nearest known white dwarf to the Sun.

Which star is the brightest?

Sirius has not always been the brightest star in the sky. It took the title from Canopus about 90,000 years ago. Before Canopus, Capella was the brightest star and, before Capella, it was Aldebaran. The brightest of the stars that held the title were Sirius’ neighbours in Canis Major, Adhara (mag. -3.99) and Mirzam (-3.65). The star that was the brightest the most times is Canopus, which will take the title again after Vega has taken its turn after Sirius.

How old is Sirius A?

Sirius A has roughly twice the Sun’s mass and 1.7 times the Sun’s radius. Its estimated age is between 237 and 247 million years, which makes the star considerably younger than the Sun (4.6 billion years). Sirius A has a visual magnitude of -1.47 and an absolute magnitude of +1.42.

What constellation is Procyon in?

Procyon, Alpha Canis Minoris (α CMi), is a binary star system with an apparent magnitude of 0.34, located at a distance of only 11.46 light years from Earth in the constellation Canis Minor. Like its brighter neighbour Sirius in Canis Major, it is one of the nearest star systems to the Sun.

What is the star class of Procyon A?

Procyon A has the stellar classification F5 IV-V, indicating an evolved star still on the main sequence, appearing white in colour. The star’s brightness, which is high for its class, indicates that the star has almost run out of hydrogen in its core and begun to expand as it continues to evolve into a subgiant.

Which is harder to observe, Sirius B or Procyon B?

The star’s existence was inferred from astrometric observations before it was confirmed visually. Procyon B is harder to observe than Sirius B because the angular separation between the two components in the Alpha CMi system is smaller, only 5 arcseconds at the most.

How far apart are the two stars in the constellation Procyon?

Their orbit is inclined at 31.1° to our line of sight. It takes the two stars within 8.9 astronomical units of each other and as far apart as 21 astronomical units. Their average separation is 15 astronomical units, almost the distance from the Sun to Uranus. Procyon (Alpha Canis Minoris), image: Wikisky.

Which star is the brightest in Canis Minor?

When was Alpha Canis Minoris A approved?

The International Astronomical Union’s (IAU) Working Group on Star Names (WGSN) officially approved the name for Alpha Canis Minoris A on June 30, 2016. Even though it formally applies only to the primary component, it is also commonly used for the entire system and for its fainter component (Procyon B).
