Zeta Oph the Runaway Star that Left a Gorgeous Bow Shock

By on Feb 3, 2020 in Pictures | 0 comments

Located 366 light-years away in the constellation of Ophiuchus is a runaway star called Zeta Ophiuchi (ζ Ophiuchi) or Zeta Oph. It’s a runaway star because it was flung out of a star system as a result of a supernova. This enormous star is about 20 times the mass of our own Sun! Not only that but our Sun’s radius is about 696,340 km and Zeta Oph is 8 times that. This star is huge but is rotating extremely fast. It’s rotating about 400 km/s where it can rotate this gargantuan mass once per Earth day! To give you some perspective our Sun rotates at 1.997 km/s or about once every 27 days. Credit: NASA Zeta Oph is relatively young from the perspective of the universe. It’s about three million years old and is an O-type star giving it that blue hue. Scientists say it’s roughly halfway through its stellar life and in the next few million years go supernova. Of...

Carnival of Space 648: Awesome Space Stories of the Week

By on Jan 24, 2020 in Carnival of Space | 0 comments

Hi space fans! Welcome to another edition of Carnival of Space! This is the 648th edition in this great community post. It’s where a group of space bloggers will help curate the best space stories around the web and create a post. I will be your host today and got some great stories from our fellow space bloggers. Let’s jump into it! Betelgeuse is Continuing to Dim! It’s Down to 1.506 Magnitude – Universe Today Betelgeuse Our first story comes from Universe Today with a story around the star called Betelgeuse. This star is well known in the sky and will also go supernova in the next 10,000-100,000 years. However, whenever you look at the Orion constellation and look for Betelgeuse a seasoned astronomer will notice this star has been dimming. Lots of speculation occurred where news reports said this star would go supernova any minute. Well, of course, this star...

5 Things Astronomers Learned About Venus that Surprised Them

By on Jan 16, 2020 in Solar System | 0 comments

It’s been a great start to 2020 as astronomers have already discovered something new about Venus. However, there is so much happening with Venus that it would be sad not to tell the world about it. Let’s jump into 5 things astronomers recently learned about Venus that really surprised them. Upper Clouds on Venus Are Vastly Different Than Originally Thought “Akatsuki’s LIR camera spotted an enormous stationary wave running completely across the globe from north to south on Venus. The camera sees heat emanating from Venus’ uppermost clouds, day or night.” Planetary Society Credit: JAXA The clouds on Venus are fascinating. They float in the troposphere between altitudes of 47 and 70 kilometres (or 29 and 43 miles) and are divided into lower, middle, and upper layers. Upper layers are interesting because when the Sun sends its solar energy these clouds absorb them!...

Rubin’s Galaxy (UGC 2885) Largest Galaxy in Local Universe?

By on Jan 6, 2020 in Galaxies | 0 comments

Located about 232 million light-years in the northern constellation Perseus is UGC 2885 or nicknamed “Rubin’s Galaxy.” This galaxy is 2.5 times wider than our own Milky Way! It also contains 10 times as many stars which results in as much 4 trillion stars! Now you really get a sense of why astronomers are referring to it as the largest galaxy known to date. Credits: NASA, ESA and B. Holwerda (University of Louisville) Rubins galaxy is enormous and really quite relaxed for a giant. The number of stars it produces is half the rate of our Milky Way. That means it’s really slowing down at the star factory. Also, the supermassive black hole in the center of it is also taking a break and not feeding on any smaller satellite galaxies. This galaxy falls under a special category called “field galaxies.” Or a galaxy that is in a remote area of space that is...

10 Amazing Discoveries that Changed Astronomy in the Last Decade

By on Dec 31, 2019 in Round Up Post | 0 comments

Astronomy has seen so much progress and change in the last decade. From SpaceX and reusable rockets to landing on comets and discovering oceans on moons. The last ten years gave us great science. However, the start of 2010 didn’t look so promising. It started off in February of 2010 with Obama cancelling the Constellation program or the mission to get back to the Moon by 2020, due to budget constraints. Nonetheless, it was a tough start and a year later the space shuttle retired signifying that NASA needed a new spacecraft to take them to the Moon, Mars and beyond. No one could really guess what these 10 amazing years would deliver to not only astronomers but the public. Let’s jump in: NASA’S CURIOSITY ROVER LANDS FAMOUSLY ON MARS Artist depiction of Curiosity Rover landing on Mars during the “7 minutes of terror.” Credit: NASA August 2012 the world has...
