A Long Exposure Hubble Image of a Galaxy Cluster Also Turned up 22 Asteroids

The Hubble Space Telescope is the oldest space telescope in operation, having spent the past twenty-eight years in orbit. Nevertheless, this mission is still hard at work revealing things about our Solar System, neighboring exoplanets, and some of the farthest reaches of the Universe. And every so often, it also captures an image that happens to turn up something interesting and unexpected

Complex Organics Molecules are Bubbling up From Inside Enceladus

The Cassini orbiter revealed many fascinating things about the Saturn system before its mission ended in September of 2017 . In addition to revealing much about Saturn’s rings and the surface and atmosphere of Titan (Saturn’s largest moon), it was also responsible for the discovery of water plumes coming from Enceladus ‘ southern polar region. The discovery of these plumes triggered a widespread debate about the possible existence of life in the moon’s interior

A Satellite With a Harpoon, Net and Drag Sail to Capture Space Junk is in Orbit and Will be Tested Soon

After almost seventy years of spaceflight, space debris has become a rather serious problem. This junk, which floats around in Low Earth Orbit (LEO), consists of the spent first rocket stages and non-functioning satellites and poses a major threat to long-term missions like the International Space Station and future space launches. And according to numbers released by the Space Debris Office at the European Space Operations Center (ESOC), the problem is only getting worse.

There’s Sand on Titan, Where Does it Come From?

Even though the Cassini orbiter ended its mission on of September 15th, 2017, the data it gathered on Saturn and its largest moon, Titan , continues to astound and amaze. During the thirteen years that it spent orbiting Saturn and conducting flybys of its moons, the probe gathered a wealth of data on Titan’s atmosphere, surface, methane lakes, and rich organic environment that scientists continue to pore over. For instance, there is the matter of the mysterious “sand dunes” on Titan, which appear to be organic in nature and whose structure and origins remain have remained a mystery.

The Universe’s Missing Matter. Found!

In the 1960s, astronomers began to notice that the Universe appeared to be missing some mass. Between ongoing observations of the cosmos and the the Theory of General Relativity , they determined that a great deal of the mass in the Universe had to be invisible. But even after the inclusion of this “dark matter”, astronomers could still only account for about two-thirds of all the visible (aka

The Martian Dust Storm Has Covered the Entire Planet

Martian dust storms, which occur during the summer season in the planet’s southern hemisphere, can get pretty intense. Over the course of the past few weeks, a global dust storm has engulfed Mars and forced the Opportunity rover to suspend operations . Given that this storm is much like the one that took place back in 2007 , which caused the Spirit rover to be lost, there have been concerns over how this storm could affect rover operations

Carnival of Space #566-567

Welcome to the 566-567th 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. We have a fantastic double-feature roundup today, so now, on to these two week’s worth of stories! Chandra: Chandra Scouts Nearest Star System for Possible Hazards Star Shredded by Rare Breed of Black Hole Red Nuggets’ are Galactic Gold for Astronomers NextBigFuture: Two new Star Trek TV shows and two limited series are in development Will future war be about ultra-massive drones swarms and super-weapons somewhat like Ender’s Game? SpaceX BFR can be used for massive space development, orbital, lunar and Mars colonization Planetaria: Life at Alpha Centauri

New Model Predicts That We’re Probably the Only Advanced Civilization in the Observable Universe

The Fermi Paradox remains a stumbling block when it comes to the search for extra-terrestrial intelligence (SETI). Named in honor of the famed physicist Enrico Fermi who first proposed it, this paradox addresses the apparent disparity between the expected probability that intelligent life is plentiful in the Universe, and the apparent lack of evidence of extra-terrestrial intelligence (ETI). In the decades since Enrico Fermi first posed the question that encapsulates this paradox (“Where is everybody?”), scientists have attempted to explain this disparity one way or another.

How an Advanced Civilization Could Stop Dark Energy From Preventing Their Future Exploration

During the 1930s, astronomers came to realize that the Universe was in a state of expansion. By the 1990s, it became learned that the rate of expansion was accelerating, giving rise to the theory of “Dark Energy”. Because of this, in the next 100 billion years, all stars within the Local Group – the part of the Universe that includes a total of 54 galaxies, including the Milky Way – will expand beyond the cosmic horizon

Could Cyanobacteria Help to Terraform Mars?

Billions of years ago, Earth’s atmosphere was much different than it is today. Whereas our current atmosphere is a delicate balance of nitrogen gas, oxygen and trace gases, the primordial atmosphere was the result of volcanic outgassing – composed primarily of carbon dioxide, methane, ammonia, and other harsh chemicals

A Meteoroid Smashed Into the Side of a Crater on Mars and Then Started a Landslide

In 2006, NASA’s Mars Reconnaissance Orbiter (MRO) established orbit around the Red Planet. Using an advanced suite of scientific instruments – which include cameras, spectrometers, and radar – this spacecraft has been analyzing landforms, geology, minerals and ice on Mars for years and assisting with other missions. While the mission was only meant to last two years, the orbiter has remained in operation for the past twelve.
