Every year, the Department of National Intelligence (DNI) releases its Worldwide Threat Assessment of the US Intelligence Community . This annual report contains the intelligence community’s assessment of potential threats to US national security and makes recommendations accordingly.
During the 1970s, scientists confirmed that radio emissions coming from the center of our galaxy were due to the presence of a Supermassive Black Hole (SMBH). Located about 26,000 light-years from Earth between the Sagittarius and Scorpius constellation, this feature came to be known as Sagittarius A*
It’s been a time of milestones for Mars rovers lately! Last month (on January 26th, 2018 ), NASA announced that the Curiosity rover had spent a total of 2,000 days on Mars , which works out to 5 years, 5 months and 21 days. This was especially impressive considering that the rover was only intended to function on the Martian surface for 687 days (a little under two years)
It’s been almost 19 years since I founded Universe Today, back in March, 1999. Back when I started, it was a primarily an email-based newsletter with an archive version on the web where people could read it if they wanted to.
Back in the late 1980’s, Voyager 2 was the first spacecraft to capture images of the giant storms in Neptune’s atmosphere. Before then, little was known about the deep winds cycling through Neptune’s atmosphere
Welcome to the 549th Carnival of Space! The Carnival is a community of space science and astronomy writers and bloggers, who submit their best work each week for your benefit. So now, on to this week’s stories! First up, over at the Chandra X Ray Observatory Blog , they have two articles about the The Billion-year Race Between Black Holes and Galaxies – from guest bloggers Mar Mezcua and Guang Yang. Then, we visit Zain Husain at the Brown Spaceman blog for his review of the amazing Falcon Heavy launch , and he discusses now Falcon Heavy could speed up science and space exploration.
Since ancient times, astronomers have looked up at the night sky and seen the Andromeda galaxy. As the closest galaxy to our own, scientists have been able to observe and scrutinize this giant spiral galaxy for millennia. By the 20th century, astronomers realized that Andromeda was the Milky Way’s sister galaxy and was moving towards us.
An astrophotographer in California has captured images of Elon Musk’s Tesla Roadster on its journey around our Sun.
On October 19th, 2017 , the Panoramic Survey Telescope and Rapid Response System -1 (Pan-STARRS-1) telescope in Hawaii announced the first-ever detection of an interstellar asteroid – I/2017 U1 (aka. ‘Oumuamua). Originally mistaken for a comet, follow-up observations conducted by the European Southern Observatory (ESO) and others confirmed that ‘Oumuamua was actually a rocky body that had originated outside of our Solar System
On February 6th, 2018 , SpaceX successfully launched its Falcon Heavy rocket into orbit. This was a momentous occasion for the private aerospace company and represented a major breakthrough for spaceflight.
It’s been 20 years since the first of the four Unit Telescopes that comprise the ESO’s Very Large Telescope (VLT) saw first light. Since the year 2000 all four of them have been in operation. One of the original goals of the VLT was to have all four of the ‘scopes work in combination, and that has now been achieved.

In July of 2020, the Mars 2020 rover – the latest from NASA’s Mars Exploration Program – will begin its long journey to the Red Planet.
New Horizons Just Took a Record Breaking Image. No Camera Has Ever Taken a Picture From This Far From Earth
In July of 2015 , the New Horizons mission made history by being the first spacecraft to rendezvous with Pluto. In the course of conducting its flyby, the probe gathered volumes of data about Pluto’s surface, composition, atmosphere and system of moons.

Welcome back to Messier Monday! Today, we continue in our tribute to our dear friend, Tammy Plotner, by looking at the intermediate spiral galaxy known as Messier 65. In the 18th century, while searching the night sky for comets, French astronomer Charles Messier kept noting the presence of fixed, diffuse objects he initially mistook for comets. In time, he would come to compile a list of approximately 100 of these objects, hoping to prevent other astronomers from making the same mistake
Roughly half a century ago, Cornell astronomer Frank Drake conducted Project Ozma , the first systematic SETI survey at the National Radio Astronomy Observatory in Green Bank, West Virginia. Since that time, scientists have conducted multiple surveys in the hopes of find indications of “technosignatures” – i.e. evidence of technologically-advanced life (such as radio communications).
Researchers Just Scanned 14 Worlds From the Kepler Mission for “Technosignatures”, Evidence of Advanced Civilizations
When it comes to looking for life on extra-solar planets , scientists rely on what is known as the “low-hanging fruit” approach. In lieu of being able to observe these planets directly or up close, they are forced to look for “biosignatures” – substances that indicate that life could exist there. Given that Earth is the only planet (that we know of) that can support life, these include carbon, oxygen, nitrogen and water
