The article examines black holes, looking at research on both stellar-mass and supermassive black holes. The article discusses the formation of black holes after the death of massive stars, how astronomers study black holes by observing X-ray-emitting binary star systems, and differences in the behavior of black holes and neutron stars. The article also looks at supermassive black holes located at the center of large galaxies, such as Sagittarius A* in the Milky Way galaxy. INSET: Track down a black hole.

This article discusses the discovery of black holes and the clues such as event horizons used by modern scientists to verify their existence. Topics include two classification types for black holes, stellar mass and super-massive, the use of X-ray binary system tracers in the identification of black holes, and the discovery of the Sagittarius A& (SGR A*) black hole that is believed to lie at the center of the Milky Way galaxy.

The article reports that South Africa's Department of Science and Technology's MeerKAT radio telescope will officially operate after a decade of construction ansd it use to study properties of Milky Way's central supermassive black hole Sagittarius A.

The article reports on the Sagittarius A * blackhole which is being targeted by Earth-sized Event Horizon Telescope and the gathering of information from April 5-14, 2017 that are stored physically to Germany's Max Planck Institute and processed at Haystack Observatory in Massachusetts.

The article offers several news briefs related to astronomy including increased size of black hole on the Sagittarius A* galaxy; gravitational waves coming from pairs of black holes circling at centers of galaxies; and global liquid water found beneath the planet Saturn's Enceladus satellite.

The article reports on the generation of two megaflares as observed by the Amherst College's Daryl Haggard and colleagues, concluding two hypothesis which include debris from torn-apart asteroid coming near to Sagittarius A as well as the generation of magnetic field lines surrounding black hole.

The article reports that the interstellar gas cloud G2 will travel close to the black hole Sagittarius A* at the center of the Milky Way galaxy, focusing on astronomers' plans to observe the event in hopes of studying the black hole.

A letter to the editor is presented in response to the article "40 Deep-Sky Targets in Sagittarius" that was published in the August 2013 issue of the magazine "Astronomy."

The article reports on the Milky Way's black hole Sagittarius A (Sgr A) and its eruption for the past two million years along with arguments involving the Magellanic Stream.

The article discusses research by astronomer Sera Markoff of the University of Amsterdam, the Netherlands and colleagues in the August 30, 2013 issue of "Science" magazine investigating the activity of the Milky Way galaxy's black hole, called Sagittarius A*, using the Chandra X-ray Observatory.

Corrections to articles in previous issues such as "Rockets rocked it" in the August 2013 issue regarding the British commercial spaceflight company Virgin Galactic and the " 40 deep-sky targets in Sagittarius" are presented.

The article discusses the supermassive black hole Sagittarius A* at the center of the Milky Way Galaxy, and a paper to be published in the journal "Monthly Notices of the Royal Astronomical Society" that suggests the black hole is absorbing comets and asteroids.

This article discusses the destruction of a gas cloud inside of the black hole Sagittarius A star (Sgr A*) at the center of the Milky Way galaxy. Topics include the gas cloud's nearest proximity to the black hole in mid-2013, the source of radiation the cloud will produce as it falls into the black hole, and the valuable information about the behavior of matter around massive objects that the event will provide.

The article discusses the planet Jupiter as it reaches opposition in the constellation Sagittarius and peak visibility on September 21, 2010 in the constellation Pisces. Topics include what astronomy observers can expect to see, such as Jupiter's moons Io, Europa, Ganymede, and Callisto, why it will take some time observing Jupiter through a telescope, such as its size, and a calendar of astronomy events in September 2010.

The article discusses the weight of the supermassive black hole at the center of the Milky Way galaxy. The black hole is named Sagittarius A* and is orbited by 28 stars. Sagitarrius A* was observed using large telescopes equipped with adaptive optics. An image taken of the center of the Milky Way by the European Southern Observatory's Very Large Telescope is also included.

The article discusses astronomical observations during the month of August which can be seen with a pair of binoculars. The Small Sagittarius Star Cloud to the north of Sagittarius's Teapot is explored. Barnard 92 and Barnard 93 are a pair of opaque, dark nebulae which first found by astronomer Edward Emerson Barnard in 1919. Barnard 92 looks like a small, oval hole on the northwestern edge of the Star Cloud. Other locations of Messier objects such as the Swan Nebula are discussed.
