Galileo and the Medicis brought Revolution and Truth

Galileo and the Medicis brought Revolution and Truth

by Jeffrey Foss, Ph.D. Practically everyone knows that Galileo is a heroic figure in the rise of modern science. Most people do not know, however, that the scientific revolution that Galileo launched relied on the support and protection of the Medicis. The very name of this family signifies the marriage of power and wealth that […]

The Sun dominates climate change

The Sun dominates climate change

  By Dr. Tim Ball and Tom Harris Why are the public generally unaware of the important research that connects variations in the output of the Sun with climate change? They should know about it, since the sun is responsible for far more climate change than anything we cause. The reason for this ignorance is […]

Farewell – NASA’s Record-Setting Rover Mission on Mars Comes to an End this Week

Farewell – NASA’s Record-Setting Rover Mission on Mars Comes to an End this Week

One of the most successful and enduring feats of interplanetary exploration, NASA’s Opportunity rover mission is at an end after almost 15 years exploring the surface of Mars and helping lay the groundwork for NASA’s return to the Red Planet. The Opportunity rover stopped communicating with Earth when a severe Mars-wide dust storm blanketed its location in […]

Our Solar System’s First Known Interstellar Object Gets Unexpected Speed Boost

Our Solar System’s First Known Interstellar Object Gets Unexpected Speed Boost

Using observations from NASA’s Hubble Space Telescope and ground-based observatories, an international team of scientists have confirmed ′Oumuamua (oh-MOO-ah-MOO-ah), the first known interstellar object to travel through our solar system, got an unexpected boost in speed and shift in trajectory as it passed through the inner solar system last year. “Our high-precision measurements of ′Oumuamua’s position revealed […]

Bright Areas on Ceres Suggest Geologic Activity

Bright Areas on Ceres Suggest Geologic Activity

The bright areas of Occator Crater — Cerealia Facula in the center and Vinalia Faculae to the side — are examples of bright material found on crater floors on Ceres. This is a simulated perspective view.

Solar System’s First Interstellar Visitor Dazzles Scientists

Artist’s concept of interstellar asteroid 1I/2017 U1 (‘Oumuamua) as it passed through the solar system after its discovery in October 2017. The aspect ratio of up to 10:1 is unlike that of any object seen in our own solar system.

NASA’s Juno spacecraft is about to peer into the depths of Jupiter’s Great Red Spot

NASA’s Juno spacecraft is about to peer into the depths of Jupiter’s Great Red Spot

We’re getting our closest view ever of the 10,000-mile-wide storm. On July 10, the Juno spacecraft will get close enough to peer beneath the veneer of Jupiter’s Great Red Spot. NASA Humankind has been ogling Jupiter’s Great Red Spot through our telescopes for more than 300 years. The Voyager and Galileo missions brought us closer […]
