In 1885, a stella nova flared into being that would prove to hail from the Andromeda Galaxy. By the time Walter Baade and Fritz Zwicky began coining the term "super-nova" in the 1930s, Edwin Hubble and his colleagues had already reported evidence of a Universe expanding faster than the ...
SN 2024advj is another Type II on the NW tip of the extremely faint, extremely thin, very low surface brightness flat galaxy UGC 604 in Andromeda. ZTF puts it around 15.6 V mag at this time. SN 2024adjp is a Type Ia in NGC 7543 in Pegasus. This is poorly placed in the evening ...
Five 24-hour VLA observations at 8.4 GHz of the Andromeda galaxy have been combined into a very sensitive radio image of the central 500″ (1.7 kpc) of M31. The resulting image presented here has a resolution of 0.2″ and an rms noise level of about 4 μJy. These observations have ...
Supernovae are important as they distribute elements heavier than iron throughout the galaxy. Supernovae are also important as a tool for scientists to measure distances in the universe. Type 1a supernova are known asstandard candlesbecause they all emit a similar type of light when they occur...
which is a component of the Virgo Supercluster. The Milky Way is the second-largest galaxy in the Local Group. The milky way has at least 100 billion planets. The most known planets are in our solar system. They are in order from closest to the farest away from the sun. Mercury, Venus...
the new instrument has so far discovered 50 small near-Earth asteroids and more than 1,100 supernovae, and it has observed more than 1 billion stars in theMilky Waygalaxy. One of the near-Earth asteroids discovered by ZTF, called 2019 AQ3, has an orbital period of just 165 days, the...
SN 2025ah, a Type IIn in an extremely faint uncatalogued face-on barred spiral galaxy in Andromeda. Per ZTF's classification, this SN's spectra suggests z=0.0815 which is on the order of 1.1 billion light years, by far the most distant SN I have successfully observed (about 35% more ...
In modern times, the interest in novae was reignited by the appearance, in 1885, of a nova in the Andromeda nebula (now named SN 1885A) [3]. This event, along with the novae discovered in the Milky Way and in several spiral nebulae in the following decades, became one of the key to...
Since the development of the telescope the field of supernova discovery has extended to other galaxies, starting with the 1885 observation of supernova S Andromedae in the Andromeda galaxy. Supernovae provide important information on cosmological distances. ...
The term "supernova" was first used by Walter Baade and Fritz Zwicky atMount Wilson Observatory, who used it in relation to an explosive event they observed, called S Andromedae (also known as SN 1885A), located in theAndromeda Galaxy. The scientists suggested that supernovas happen when or...
