dwarf elliptical galaxy facts
11.2), and the supergiant elliptical radio galaxy NGC 6251 (mag. EGS-zs8-1 is a high-redshift Lyman-break galaxy found at the northern constellation of Boötes. It has an apparent magnitude of 14.2 and is approximately 2.51 million light years distant from the solar system. It is believed that a great deal of the mass in an elliptical galaxy is due to the presence of a central black hole. 11.9), a dwarf spheroidal galaxy discovered in 1955, the barred spiral galaxy NGC 6217 (mag. This galaxy was discovered by William Hershel in 1784. Atoms for Peace Galaxy (NGC 7252) Atoms for Peace Galaxy, catalogued as NGC 7252, is a peculiar elliptical galaxy, approximately 220 million light years distant. In our solar system we have eight planets: Mercury, Venus, Earth, and Mars are the inner rocky planets. This page is a continuously updated list of the most incredible, awe-inspiring and unbelievable facts about space. (Objects smaller than red dwarf stars are called brown dwarfs and do not shine through the thermonuclear fusion of hydrogen.) It is suspected to be a satellite galaxy of Messier 33, the Triangulum Galaxy, located in Triangulum constellation. A few examples of these satellite galaxies are the Canis Major Dwarf Galaxy, the Sagittarius Dwarf Elliptical Galaxy (SagDEG), the Large Magellanic Cloud, and the Small Magellanic Cloud. Red dwarf star, also called M dwarf or M-type star, the most numerous type of star in the universe and the smallest type of hydrogen-burning star.. Red dwarf stars have masses from about 0.08 to 0.6 times that of the Sun. NGC 3384 is an elliptical galaxy that was discovered in 1784 by William Herschel. Notable galaxies in the constellation include the Ursa Minor Dwarf (mag. Another large body is Pluto, now classified as a dwarf planet or plutoid. [citation needed They can also form in different shapes such as elliptical galaxies and spiral galaxies. The Milky Way galaxy, the one that our solar system resides in, is classified as a spiral galaxy. It has an apparent magnitude of 11.9. Galaxy, any of the systems of stars and interstellar matter that make up the universe. Check out these other interesting space facts about the Dwarf Planet, Pluto. NGC 7814. ... elliptical, spiral & irregular. The most fascinating feature of this galaxy is its jet, which is visible in optical light as well as x-rays and radio emissions. In recent years, astronomers have designed a new class called the “dwarf planets.” This galaxy is situated at around 20.5 million light-years away from us, and it has an apparent magnitude of 12.6. Pluto was reclassified from a planet to a dwarf planet in 2006. NGC 3384. These objects all orbit the sun in roughly circular orbits that lie in the same plane, the ecliptic (Pluto is an exception; it has an elliptical … One of these is a dwarf irregular galaxy named IC 4710 , found in the constellation Pavo. The majority of irregular galaxies are very bright, which is a result of the gas and dust in them. An elliptical galaxy is the most common type of galaxy, has a roundish shape, and demonstrates little or no star formation. Atypical for a dwarf elliptical galaxy, NGC 185 contains young clusters of stars and shows evidence of star formation that occurred in the cluster until recently. It is heavier than most other planets by a long distance, but it still only has 1/3 the mass of Jupiter. Jupiter and Saturn are the outer gas giants. Saturn is the sixth planet from the Sun, only Uranus and Neptune are further away. In May 2015, EGS-zs8-1 had the highest spectroscopic redshift of any known galaxy, meaning EGS-zs8-1 was the most distant and the oldest galaxy observed. ; Saturn has a radius of 36,183.7 miles (58,232 kilometers), which makes it the second largest planet after Jupiter.Saturn’s mass is 95x that of Earth. ... (M-33), the Omega Centauri and the Sagittarius Dwarf Spheroidal Galaxy. They vary in size with some containing millions of stars while others could contain as many as a trillion. Caldwell 17 or NGC 147 is another dwarf spheroidal galaxy in Cassiopeia. Galaxy: A galaxy is a large group of stars, dust, gas and dark matter held together by gravity. More than 80% of this galaxy’s stars appear to be Population II stars, which are over one billion years old. It is by far the most important source of energy for life on Earth.Its diameter is about 1.39 million kilometres (864,000 miles), or 109 times that of Earth. What makes the Andromeda Galaxy unique is that it is the nearest 'non-satellite' and large spiral galaxy that can be considered an equal of the Milky Way Galaxy. The Andromeda Galaxy (IPA: / æ n ˈ d r ɒ m ɪ d ə /), also known as Messier 31, M31, or NGC 224 and originally the Andromeda Nebula (see below), is a barred spiral galaxy approximately 2.5 million light-years (770 kiloparsecs) from Earth and the nearest major galaxy to the Milky Way. Space is amazing. Messier 87 Galaxy Facts The massive galaxy M87 is the most spectacular example of an elliptical galaxy we can see from Earth. It has an apparent magnitude of 11.6. This gas and dust means that many stars are formed within an irregular galaxy, giving them their brightness. The Aquarius Dwarf is one of the rare galaxies that display a blueshift; it is moving toward the Milky Way Galaxy at 137 km/s. NGC 7814, also known as Caldwell 43, or UGC 8, is a spiral galaxy located at around 40 million light-years away from us. Saturn Facts. NGC 23 is a spiral galaxy located at around 173.5 million light-years away from us. The Sun is the star at the center of the Solar System.It is a nearly perfect sphere of hot plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy mainly as visible light and infrared radiation. These galaxies have very little activity and contain mostly old stars of low mass, because there … A belt of asteroids (minor planets made of rock and metal) lies between Mars and Jupiter. In July 2015, EGS-zs8-1 was surpassed by EGSY8p7 (EGSY-2008532660). An elliptical galaxy can be nearly round or long and cigar shaped. The smallest are dwarf elliptical galaxies, which can be less than 10 percent of the size of the Milky Way. 14.3). The best time of year to see the stars and deep sky objects of Ursa Minor is during the month of June. Pisces Dwarf (PGC 3792) The Pisces Dwarf is an irregular dwarf galaxy that is a member of the Local Group of galaxies. Many such assemblages are so enormous that they contain hundreds of billions of stars. Virtually all galaxies appear to have been formed soon after the universe began, and they pervade all space that is viewable by modern telescopes. Uranus and Neptune are the outer ice giants. Space Facts. The sheer vastness of it, along with the trillions upon trillions of objects in the many billion galaxies of the universe is almost incomprehensible to the human brain. It is roughly 2.53 million light-years distant from the earth. Our Milky Way galaxy has more planets than it has stars.
