Opportunity Just Saw its 5,000th Sunrise on Mars

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)

Carnival of Space #549

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.

Interstellar Asteroid ‘Oumuamua Had a Violent Past

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

Messier 66 – the NGC 3627 Intermediate Spiral Galaxy

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

If We Receive a Message From Aliens, Should We Delete it Without Reading it?

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
