- Long Island (Wikivoyage)
Long Island stretches eastward from New York City in the Metro New York region. The island is approximately 115 mi (185 km) long from Brooklyn and Queens at the western end, to Montauk at the easternmost point. At its widest, the island is about 20 mi (32 km) from north to south. While Long Island geographically includes the New York City boroughs of Brooklyn and Queens, and the more suburban counties of Nassau and Suffolk, colloquially the term is often applied only to Nassau and Suffolk counties in New York State.
- Messier 81 (Wikipedia)
Messier 81 (also known as NGC 3031 or Bode’s Galaxy) is a grand design spiral galaxy about 12 million light-years away in the constellation Ursa Major. It has a D25 isophotal diameter of 29.44 kiloparsecs (96,000 light-years). Because of its relative proximity to the Milky Way galaxy, large size, and active galactic nucleus (which harbors a 70 million M☉ supermassive black hole), Messier 81 has been studied extensively by professional astronomers. The galaxy’s large size and relatively high brightness also makes it a popular target for amateur astronomers. In late February 2022, astronomers reported that M81 may be the source of FRB 20200120E, a repeating fast radio burst.
