Latest Messier objects Stories
ESO astronomers using the Very Large Telescope (VLT) reported today that they have captured a detailed image of the Toby Jug Nebula.
Astronomers have been observing the Whirlpool Galaxy since the 18th century, but they’ve never seen it like this.
known as M101, the galaxy lies 21 million light-years away in the constellation Ursa Major. It measures 170 000 light-years across – nearly twice the diameter of our own Milky Way Galaxy – and contains at least a trillion stars. About a billion of these stars could be similar to our own Sun.
Astronomers presented research on Wednesday at the American Astronomical Society (AAS) about how the Cat's Paw Nebula is experiencing a "baby boom."
The Hubble Space Telescope has provided one of the most detailed images of the Ring Nebula so far, allowing scientists to construct a model of the nebula in 3D.
Astronomers have found that a region of space known as the Wing has fewer “metals” (elements with more than two protons in the nucleus) compared to most other areas within our own Milky Way galaxy. There are also relatively lower amounts of gas, dust and stars in the Wing compared to the Milky Way.
A stunning new image of the spiral galaxy Messier 77 captured by the Hubble Space Telescope was released today. The image of one of the most famous and well-studied galaxies highlights the pockets of star formation along its arms.
Astronomers have unveiled a new image of recently formed bright blue stars in the cluster NGC 2547.
The NGC 5866, located in the Draco constellation, is named after the galaxy with the highest magnitude however some catalogs list NGC 5907 as the brightest member. The M51 Group and the M101 Group are NGC 5866 closest neighbor. The distances between these groups are similar which suggest the three groups are part of a single large, loose, elongated group. However, most identification methods consider them separate.
The M101 Group, one of many in the Virgo Supercluster, is located in Ursa Major and named after the brightest galaxy in the group, the Pinwheel Galaxy (M101). The group is composed mostly of members that are companions of the Pinwheel Galaxy. The M51 Group and the NGC 5866 Group are M101's closest neighbor. The distances between these groups are similar which suggest the three groups are part of a single large, loose, elongated group. However, most identification methods consider them...
The M51 Group, located in Canes Venatici, is named after the brightest galaxy in the group, the Whirlpool Galaxy (M51A). The few other notable members include the companion galaxy to the Whirlpool Galaxy (M51B) and the Sunflower Galaxy (M63).
Planetary Nebula -- A planetary nebula is an astronomical object that usually appears nebulous and disk-like in low-resolution observations. Because of this appearance, similar to the appearance of planets in early observations, the "planetary" adjective was attached and has since been retained for historical consistency. According to current observations and models, planetary nebulae in fact have little to do with planets. Instead, as a small star (less than a few times the mass...
Galaxy -- Stars are almost always found in collections called galaxies, together with gas, dust, and large amounts of dark matter detected by its gravitational effects. These are all held together by gravitational attraction and orbit a common centre. There is some evidence that black holes may exist at the centre of some or most galaxies. Galaxies come in three main types: ellipticals, spirals, and irregulars. A slightly more extensive description of galaxy types is given by the Hubble...
