For Curiosity, it's Mars or bust

Blog: Lost in the horror

Obviously, the 43rd anniversary of Neil Armstrong and Buzz Aldrin landing on the moon was not mentioned Friday. But to me, it became even more important to remember the Apollo 11 lunar landing because it provided needed contrast to what human beings are capable of.

The 'Supermoon' and Venus head toward the Sun

On May 20 there will be an annular eclipse of the Sun that will be visible for much of the globe, but not the easternmost U.S. In an annular eclipse the New Moon cannot cover the Sun completely so a "ring" is seen around the Sun.

See Venus in broad daylight

The key is to have Venus as far from the Sun and its glare as possible and have a bright blue sky. It also is a big help when you have a celestial beacon nearby such as the Moon to help you spot the second planet from the Sun.

A crowded universe

For many years, astronomers thought it to be a good possibility that planets other than those in our own solar system existed around other stars. The problem was that they needed proof to confirm the theory and exoplanet ponderings. It took the decades-long technological evolution of our instruments, telescopes, computers and eventually spacecraft for astronomers to get into the realm of exoplanets.
