Another Monster Black Hole Found in the Milky Way

At the center of the Milky Way Galaxy resides the Supermassive Black Hole (SMBH) known as Sagittarius A* . This tremendous black hole measures an estimated 44 million km in diameter, and has the mass of over 4 million Suns. For decades, astronomers have understood that most larger galaxies have an SMBH at their core, and that these range from hundreds of thousands to billions of Solar Masses.

Researchers Tackle Question of How the Universe Became Filled With Light

In accordance with the Big Bang model of cosmology , shortly after the Universe came into being there was a period known as the “Dark Ages”. This occurred between 380,000 and 150 million years after the Big Bang, where most of the photons in the Universe were interacting with electrons and protons. As a result, the radiation of this period is undetectable by our current instruments – hence the name

Preparations for Deployment of InSight Lander to Mars are Rampting Up!

This summer has been a busy time for NASA. At present, the agency is making the final preparations for the Cassini mission ‘s plunge into Saturn’s atmosphere, monitoring the large Near-Earth Asteroid that recently made a flyby of Earth , marking the 40th anniversary of the historic Voyager missions , and hosting the Summer of Mars at the Kennedy Space Center. In addition to all that, engineers at the Jet Propulsion Laboratory in Pasadena, California, are busy preparing the Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) Lander for its scheduled launch in 2018

The Crux Constellation

Welcome to another edition of Constellation Friday! Today, in honor of the late and great Tammy Plotner, we take a look at the “Southern Cross” – the Crux constellation. Enjoy! In the 2nd century CE, Greek-Egyptian astronomer Claudius Ptolemaeus (aka

Hubble Spots First Indications of Water on TRAPPIST-1s Planets

In February of 2017 , astronomers from the European Southern Observatory (ESO) announced the discovery of seven rocky planets around the nearby star of TRAPPIST-1. Not only was this the largest number of Earth-like planets discovered in a single star system to date, the news was also bolstered by the fact that three of these planets were found to orbit within the star’s habitable zone .

NASA’s Plan to Explore Venus with a “SteamPunk” Rover

Venus is one hellish place! Aside from surface temperatures hot enough to melt lead – as high as 737 K (462 °C; 864 °F) – there’s also the sulfuric acid droplets and extreme pressure conditions (92 times that of Earth’s) to contend with! Because of these hostile conditions, exploring Venus’ surface and atmosphere has been an ongoing and significant challenge for space agencies. Hence why NASA’s Jet Propulsion Laboratory (JPL) is looking at some truly innovative and unconventional ideas for future missions to Venus. One of them is the second-generation concept known as the Automaton Rover for Extreme Environments (AREE)

Breakthrough Detects Repeating Fast Radio Bursts Coming from Distant Galaxy

In July of 2015, Russian billionaire Yuri Milner announced the creation of Breakthrough Listen , a decade-long project that would conduct the largest survey to date for signs of extra-terrestrial communications (ETI). As part of his non-profit organization, Breakthrough Initiatives , this survey would rely on the latest in instrumentation and software to observe the 1,000,000 closest stars and 100 closest galaxies
