The Triangulum Constellation

A grand majority of the constellations we know today come from the second century when the Greek astronomer Ptolemy created a catalog with 48 constellations. Because of his location, these constellations only included the ones he could see in Europe and with the naked eye as the telescope wouldn’t be invented for another 1,400 years.

The Summer Triangle

Spiral galaxy M33 is located in the triangle-shaped constellation Triangulum , earning it the nickname the Triangulum galaxy. About half the size of our Milky Way galaxy, M33 is the third-largest member of our Local Group of galaxies following the Andromeda galaxy (M31) and the Milky Way.

What is the magnitude of M33?

M33 has a relatively bright apparent magnitude of 5.7, making it one of the most distant objects that keen-eyed observers can view with the unaided eye (under exceptionally clear and dark skies). Although a telescope will start to reveal some of M33’s spiral features, the diffuse galaxy is actually easiest to examine with low magnification and a wide field of view, such as through binoculars. It is best observed in October.

Is Triangulum a galaxy?

The Triangulum galaxy’s orderly spiral structure displays few signs of interactions with nearby galaxies. However, that could change in the future. Only slightly farther away from us than the Andromeda galaxy, about 3 million light-years from Earth, M33 is a suspected gravitational companion to Andromeda, and both galaxies are moving toward our own.

Who was the first person to catalog M33?

Although others may have viewed the galaxy earlier, Charles Messier was the first to catalog M33 after observing it in August 1764. In the 1920s, astronomer Edwin Hubble studied dozens of variable stars (those that periodically change brightness) in M33, which helped him to estimate the object’s distance and prove that M33 is not a nebula within our own galaxy, as previously suspected, but actually a separate galaxy outside our own.

What star is the brightest?

Vega is an O-type star that is about 23 times the mass of our Sun and is the brightest star in the constellation Cygnus. It has run out of hydrogen its core and will begin to fuse helium in its core when it gets hot enough to do so. Eventually, it will expand to become a very bright red supergiant. It still looks blue-white to us, but over the next million years or so its color will change and it may end up exploding as a supernova of some kind.

What is the summer triangle?

How old is Altair?

Altair is a young star (about a billion years old) that is currently passing through an interstellar cloud of gas and dust called G2. It lies about 17 light-years away from us, and astronomers have observed it to be a flattened star. It’s oblate (flat-looking) because the star is a fast rotator, meaning it spins very rapidly on its axis. It took quite a few observations with special instruments before astronomers could figure out its rotation and the effects it causes. This bright star, which is the first one for which observers have a clear, direct image, is about 11 times brighter than the Sun and nearly twice as massive as our star.

Why does Vega glow in infrared light?

Vega and its dust disk, as seen by Spitzer Space Telescope. The disk glows in infrared light because it is warmed by its star. NASA/Spitzer/CalTech

How old is Vega?

It is the brightest star in Lyra, and the fifth brightest star in the entire night sky. Vega is a fairly young blue-white star, only about 455 million years old. That makes it much younger than the Sun. Vega is twice the mass of the Sun, and due to that, it will burn through its nuclear fuel more rapidly.

What are the three stars in the summer triangle?

What are the names of the stars in the triangle?

Three stars make up the triangle: Deneb, Vega and Altair . Deneb is the farthest away from Earth among these three, and is the brightest star in the constellation Cygnus; it forms the tail of the Swan. Coincidentally, Deneb is also the head of another asterism known as the Northern Cross, which is contained in Cygnus.

How far away is Deneb from Altair?

The three stars have been recognized for some time as having similar brightness (although it should be noted that Deneb is about 1,400 light-years away while Vega and Altair are roughly 20 light-years away each, showing how much more luminous Deneb is.) [ Related: Brightest Stars: Luminosity & Magnitude]

What is the brightest star in the sky?

Vega is the brightest star of an otherwise dim and small constellation, Lyra (the Harp). Vega is one of the brightest stars in the night sky. (Sirius is the brightest in the night sky, but appears in the winter of the Northern Hemisphere.) About 12,000 years ago, it used to be the North Star due to an effect called precession, where the Earth’s north-pointing direction changes due to a wobbling axis.

Which constellation is the brightest star in the constellation Aquilia?

Rounding out the asterism is Altair, which is the brightest star in the constellation Aquilia (the Eagle.) Altair is one of the brightest close stars to Earth.

Does Altair rotate?

Altair also rotates fairly quickly and has flattening at its poles, which astronomers spotted in 2006 using long-baseline interferometery (which links together numerous telescopes to together look at a region of the sky.) In 2014, the XMM-Newton mission observed Altair, showing that the star has a corona (outer atmosphere) that changes depending on magnetic and rotational activity.

Is Vega a fast rotating star?

Vega is also a fast rotater. In 2006, astronomers discovered it is whirling around so quickly — every 12.5 hours — that its equator is many thousand degrees cooler than its poles. If the star rotated just 10 percentage points faster, it would be at its critical rotation speed — the point at which the star would self-destruct due to its fast rotation. The star is sometimes cited in the literature as a comparison to the rotation of other stars, such as the slowly rotating KIC 11145123.

What is a Constellation?

Constellations are groups of stars that form patterns in the night sky, often named after animals, creatures, or mythological people resembling the outline or pattern. The word ‘constellation’ comes from the Latin ‘constellacio’ which means ‘set of stars’.

Another example of an asterism in the night sky is The Big Dipper. This pattern of stars is one of the most familiar sights in the northern sky. The Big Dipper is a prominent group of stars within the larger constellation of Ursa Major (The Great Bear).

What is the difference between a constellation and an asterism?
