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 .
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)
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
Back in 2012, Elon Musk proposed a revolutionary idea that he described as the “ fifth form of transportation “.
The study of extra-solar planets has turned up some rather interesting candidates in the past few years. As of August 1st, 2017, a total of 3,639 exoplanets have been discovered in 2,729 planetary systems and 612 multiple planetary systems.

In the coming decades, NASA has some rather bold plans for space exploration. By the 2030s, they hope to mount their “ Journey to Mars “.
Welcome back to Messier Monday! We continue our tribute to our dear friend, Tammy Plotner, by looking at the “Summer Rose Star”, other known as the globular star cluster of Messier 55. Enjoy! In the 18th century, while searching the night sky for comets, French astronomer Charles Messier kept noting the presence of fixed, diffuse objects in the night sky
In October of 2018, the James Webb Space Telescope (JWST) will be launched into orbit. As part of NASA’s Next Generation Space Telescope program, the JWST will spend the coming years studying every phase of cosmic history
Cold-War Era Derived ICBM Blasts Military ORS-5 Surveillance and Space Junk Tracking Satellite to Orbit
ICBM derived Minotaur IV overnight launch of the ORS-5 space situational awareness and debris tracking satellite for the U.S. Air Force at 2:04 a.m. EDT on August 26, 2017 from Cape Canaveral Air Force Station in Florida
KIC 8462852 (aka. Tabby’s Star) continues to be a source of both fascination and controversy.
In late 1970s and early 80s, scientists got their first detailed look at Saturn’s largest moon Titan . Thanks to the Pioneer 11 probe, which was then followed by the Voyager 1 and 2 missions, the people of Earth were treated to images and readings of this mysterious moon. What these revealed was a cold satellite that nevertheless had a dense, nitrogen-rich atmosphere
Threat Tracking USAF Satellite Launching Nighttime Aug 25 on Cape Debut of Retired ICBM Minotaur Rocket: Watch Live
An Orbital ATK Minotaur IV rocket carrying the ORS-5 USAF surveillance satellite is slated for its maiden liftoff from Cape Canaveral Air Station, Florida at 11:15 p.m. EDT on August 25, 2017 on a retired ICBM
When stars exhaust their supply of hydrogen fuel, they exit the main sequence phase of their evolution and enter into what is known as the Red Giant Branch (RGB) phase. This is characterized by the stars expanding significantly and becoming tens of thousands of times larger than our Sun. They also become dimmer and cooler, which lends them a reddish-orange appearance (hence the name).

Every planet in our Solar System interacts with the stream of energetic particles coming from our Sun. Often referred to as “solar wind”, these particles consist mainly of electrons, protons and alpha particles that are constantly making their way towards interstellar space .
SpaceX CEO and founder Elon Musk made public the first official photo of the commercial space company’s spacesuit design with a post on Instagram today. He indicated he’ll have more details soon and said this first ‘reveal’ isn’t just a prototype design; it’s a real, working spacesuit. “Worth noting that this actually works (not a mockup)” Musk said.
For more than three decades, the internal structure and evolution of Uranus and Neptune has been a subject of debate among scientists. Given their distance from Earth and the fact that only a few robotic spacecraft have studied them directly, what goes on inside these ice giants is still something of a mystery. In lieu of direct evidence, scientists have relied on models and experiments to replicate the conditions in their interiors
