Astronomy and Society

Astronomy might be about the heavens, but it has effects right here on Earth, too. Some of these impacts are on the world scale — such as the meteoroid that detonated over Chelyabinsk, Russia in 2013. Others are less blockbuster, such as the growing race to mine asteroids or the successful launch of homemade satellites. And then there are the hoaxes that fill our inboxes from well-meaning friends and the hype over putative “supermoons“.

Here you’ll find the latest news and blogs on the things in astronomy that touch our lives. Whether it be NASA space policy or the facts behind Daylight Saving Time, we’ll keep you up to speed on how you can be involved in astronomy and how astronomy endeavors are affecting you and our society.

Astronomers warn that it's not a question of "if" Earth will be hit by an asteroid, but "when." If a private group of space veterans has its way, a Sun-orbiting spacecraft will find threatening objects decades before they can strike us.
