1SWASP J140747.93-394542.6

1SWASP J140747.93-394542.6 (often abbreviated 1SWASP J140747 or J1407) is a star similar to the Sun located in the constellation of Centaurus at a distance of about 420 light years from Earth. A relatively young star, its age is estimated to be 16 million years, and its mass is about 90% that of the Sun's. The star has an apparent magnitude of 12.3 and requires a telescope to be seen. The star's name comes from the SuperWASP (Wide Angle Search for Planets) program and the stars RA/Dec.

J1407 is probably orbited by at least one known body, 1SWASP J1407b (J1407b), thought to be either a large gas giant planet or a brown dwarf with an immense ring system.

1SWASP J140747.93-394542.6 b

The discovery of the J1407 system and its unusual eclipses were first reported by a team led by University of Rochester astronomer Eric Mamajek in 2012. The existence and parameters of the ring system around the substellar companion J1407b were deduced from the observation of a very long and complex eclipse of the previously anonymous star J1407 during a 56-day period during April and May 2007. The low-mass companion J1407b has been referred to as a "Saturn on steroids" or “Super Saturn” due to its massive system of circumplanetary rings with a radius of approximately 90 million km (0.6 AU). The orbital period of the ringed companion J1407b is estimated to be around a decade (constrained to 3.5 to 13.8 years), and its most probable mass is approximately 13 to 26 Jupiter masses, but with considerable uncertainty. The ringed body can be ruled out as being a star with mass of over 80 Jupiter masses at greater than 99% confidence. The ring system has an estimated mass similar to that of the Earth. A gap in the ring system at about 61 million km (0.4 AU) from its centre is considered to be indirect evidence of the existence of an exomoon with mass up to 0.8 Earth masses.

Generic top-level domain

Generic top-level domains (gTLDs) are one of the categories of top-level domains (TLDs) maintained by the Internet Assigned Numbers Authority (IANA) for use in the Domain Name System of the Internet. A top-level domain is the last label of every fully qualified domain name. They are called generic for historic reasons; initially, they were contrasted with country-specific TLDs in RFC 920.

The core group of generic top-level domains consists of the com, info, net, and org domains. In addition, the domains biz, name, and pro are also considered generic; however, these are designated as restricted, because registrations within them require proof of eligibility within the guidelines set for each.

Historically, the group of generic top-level domains included domains, created in the early development of the domain name system, that are now sponsored by designated agencies or organizations and are restricted to specific types of registrants. Thus, domains edu, gov, int, and mil are now considered sponsored top-level domains, much like the themed top-level domains (e.g., jobs). The entire group of domains that do not have a geographic or country designation (see country-code top-level domain) is still often referred to by the term generic TLDs.

Pop (U2 album)

Pop is the ninth studio album by Irish rock band U2. It was produced by Flood, Howie B, and Steve Osborne, and was released on 3 March 1997 on Island Records. The album was a continuation of the band's 1990s musical reinvention, as they incorporated alternative rock, techno, dance, and electronica influences into their sound. Pop employed a variety of production techniques that were relatively new to U2, including sampling, loops, programmed drum machines, and sequencing.

Recording sessions began in 1995 with various record producers, including Nellee Hooper, Flood, Howie B, and Osborne, who were introducing the band to various electronica influences. At the time, drummer Larry Mullen, Jr. was inactive due to a back injury, prompting the other band members to take different approaches to songwriting. Upon Mullen's return, the band began re-working much of their material but ultimately struggled to complete songs. After the band allowed manager Paul McGuinness to book their upcoming 1997 PopMart Tour before the record was completed, they felt rushed into delivering it. Even after delaying the album's release date from the 1996 Christmas and holiday season to March 1997, U2 ran out of time in the studio, working up to the last minute to complete songs.

Miami station (Amtrak)

Miami is a train station in Miami-Dade County, Florida, on the border of Miami and Hialeah. It serves Amtrak, the national passenger rail service of the United States, and is the southern end of the Silver Meteor and Silver Star trains. It is scheduled to be replaced by Miami Central Station in summer 2016.

The Miami station was built on the site of the former Seaboard Air Line Railroad southern coach yards, to which Amtrak moved in 1977 when it abandoned the original Seaboard station at 2210 NW 7th Avenue in Allapattah, two miles north of downtown. Constructed in 1978, the building is one of many built under Amtrak's Standard Stations Program, an attempt to create a unified brand and identity for the company's passenger facilities in its early years. It is considered a Type 300A station, meaning it was designed to accommodate at least 300 passengers at the busiest hour of the day. Within the Amtrak system, it is similar to the station in Minneapolis-St. Paul, also built in 1978.
