No, a Dinosaur Skull Hasn’t Been Found on Mars: Why We See Familiar Looking Objects on the Red Planet

What is up with the fossils on Mars? Found – a dinosaur skull on Mars? Discovered – a rat, squirrel or gerbil on Mars? In background of images from Curiosity, vertebrae from some extinct Martian species? And the human skull, half buried in photos from Opportunity Rover. All the images are made of stone from […]

Winds of Supermassive Black Holes Can Shape Galaxy-Wide Star Formation

The combined observations from two generations of X-Ray space telescopes have now revealed a more complete picture of the nature of high-speed winds expelled from super-massive black holes. Scientist analyzing the observations discovered that the winds linked to these black holes can travel in all directions and not just a narrow beam as previously thought. The black holes […]

A Recipe for Returning Pluto to Full Planethood

A storm is brewing, a battle of words and a war of the worlds. The Earth is not at risk. It is mostly a civil dispute, but it has the potential to influence the path of careers. In 2014, a Harvard led debate was undertaken on the question: Is Pluto a planet. The impact of the definition […]

A Star Passed Through the Solar System Just 70,000 Years Ago

Astronomers have reported the discovery of a star that passed within the outer reaches of our Solar System just 70,000 years ago, when early humans were beginning to take a foothold here on Earth. The stellar flyby was likely close enough to have influenced the orbits of comets in the outer Oort Cloud, but Neandertals […]

Nobody Knows What These Mysterious Plumes are on Mars

In March 2012, amateur astronomers began observing unusual clouds or plumes along the western limb of the red planet Mars. The plumes, in the southern hemisphere rose to over 200 kilometers altitude persisting for several days and then reappeared weeks later. So a group of astronomers from Spain, the Netherlands, France, UK and USA have […]

How We’ve ‘Morphed’ From “Starry Night” to Planck’s View of the BICEP2 Field

From the vantage point of a window in an insane asylum, Vincent van Gogh painted one of the most noted and valued artistic works in human history. It was the summer of 1889. With his post-impressionist paint strokes, Starry Night depicts a night sky before sunrise that undulates, flows and is never settled. Scientific discoveries […]

Elon Musk and the SpaceX Odyssey: the Path from Falcon 9 to Mars Colonization Transporter

In Kubrick’s and Clark’s 2001 Space Odyssey, there was no question of “Boots or Bots”[ref]. The monolith had been left for humanity as a mileage and direction marker on Route 66 to the stars. So we went to Jupiter and Dave Bowman overcame a sentient machine, shut it down and went forth to discover the […]

There’s a crack forming on Rosetta’s 67P. Is it breaking up?

Not all comets breakup as they vent and age, but for Rosetta’s comet 67P, the Rubber Duckie comet, a crack in the neck raises concerns. Some comets may just fizzle and uniformly expel their volatiles throughout their surfaces. They may become like puffballs, shrink some but remain intact. Comet 67P is the other extreme. The expulsion of […]
