In the past few decades, thanks to improvements in ground-based and space-based observatories, astronomers have discovered thousands of planets orbiting neighboring and distant stars (aka. extrasolar planets )
At the center of our galaxy resides a Supermassive Black Hole (SMBH) known as Sagittarius A . Based on ongoing observations, astronomers have determined that this SMBH measures 44 million km (27.34 million mi) in diameter and has an estimated mass of 4.31 million Solar Masses. On occasion, a star will wander too close to Sag A and be torn apart in a violent process known as a tidal disruption event (TDE)

When it comes to the dream of commercial space exploration and space tourism, a few names really stand out. In addition to Elon Musk and Jeff Bezos, you have Richard Branson – the founder and CEO of the Virgin Group.
NASA photographers have always understood that taking pictures of space launches is a risky business. No one is more familiar with this than Bill Ingalls, a NASA photographer who has taking pictures for the agency for the past 30 years
Astronomers Observe a Pulsar 6500 Light-Years From Earth and See Two Separate Flares Coming off its Surface
Astronomy can be a tricky business, owing to the sheer distances involved. Luckily, astronomers have developed a number of tools and strategies over the years that help them to study distant objects in greater detail.
Pluto has been the focus of a lot of attention for more than a decade now. This began shortly after the discovery of Eris in the Kuiper Belt, one of many Kuiper Belt Objects (KBOs) that led to the “Great Planetary Debate” and the 2006 IAU Resolution
Remember the really cool Saturn V rocket set released by LEGO last year ?
Our understanding of distant stars has increased dramatically in recent decades. Thanks to improved instruments, scientists are able to see farther and clearer, thus learning more about star systems and the planets that orbit them (aka
Ever since NASA announced that they had created a prototype of the controversial Radio Frequency Resonant Cavity Thruster (aka.
Oumuamua was Just the Beginning. Astronomers Find an Interstellar Asteroid Orbiting Retrograde near Jupiter.
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.
When low- to middleweight stars like our Sun approach the end of their life cycles they eventually cast off their outer layers, leaving behind a dense, white dwarf star. These outer layers became a massive cloud of dust and gas, which is characterized by bright colors and intricate patterns, known as a planetary nebula.

This week’s Carnival of Space is hosted by me at the CosmoQuest blog . Click here to read Carnival of Space #562 And if you’re interested in looking back, here’s an archive to all the past Carnivals of Space . If you’ve got a space-related blog, you should really join the carnival.
Neutron stars are famous for combining a very high-density with a very small radius. As the remnants of massive stars that have undergone gravitational collapse, the interior of a neutron star is compressed to the point where they have similar pressure conditions to atomic nuclei.
In 1990, the Voyager 1 spaceprobe took a picture of Earth when it was about 6.4 billion km (4 billion mi) away. In this image, known as the “ pale blue dot “, Earth and the Moon appeared as mere points of light because of the sheer distance involved.
Fast Radio Bursts (FBRs) have fascinated astronomers ever since the first one was detected in 2007. This event was named the “Lorimer Burst” after it discoverer, Duncan Lorimer from West Virginia University.
Jupiter’s moon Europa continues to fascinate and amaze! In 1979, the Voyager missions provided the first indications that an interior ocean might exist beneath it’s icy surface.
