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 […]

What’s Inside Ceres? New Findings from Gravity Data

What’s Inside Ceres? New Findings from Gravity Data

In the tens of thousands of photos returned by NASA’s Dawn spacecraft, the interior of Ceres isn’t visible. But scientists have powerful data to study Ceres’ inner structure: Dawn’s own motion. Since gravity dominates Dawn’s orbit at Ceres, scientists can measure variations in Ceres’ gravity by tracking subtle changes in the motion of the spacecraft. […]

Pluto: The Ice Plot Thickens

Pluto: The Ice Plot Thickens

The latest spectra from New Horizons Ralph instrument reveal an abundance of methane ice, but with striking differences from place to place across the frozen surface of Pluto. “We just learned that in the north polar cap, methane ice is diluted in a thick, transparent slab of nitrogen ice resulting in strong absorption of infrared […]
