What would humanity do if an asteroid were headed for Earth? The documentary takes viewers inside the real-life efforts of scientists and engineers working to detect, track, and mitigate potential asteroid threats. Featuring firsthand accounts from experts on the front lines, the film reveals the science, technology, and personal dedication behind planetary defense. The film also showcases the teamwork that drives this critical global effort.
Debuting on NASA+ Wednesday, April 16, NASA is inviting the public to participate in a special YouTube Premiere event at 4:30 p.m. EDT. During this interactive screening, viewers can watch the first public showing of the film together and ask questions to NASA planetary defense experts.
To engage audiences further, NASA is providing digital creators with a toolkit that includes resources, activities, and ways to join the mission of planetary defense.
Established in 2016, NASA’s Planetary Defense Coordination Office leads the agency’s mission to find, track, and understand asteroids and comets that could pose a risk to Earth.

This Star Might Have Been Thrown Out of a Globular Cluster by an Intermediate Mass Black Hole
Astronomers are on the hunt for those in-between black holes, not the small stellar ones or the supermassive ones, but something right in the middle. Recently, a group of scientists spotted a star travelling at high velocity out of the globular cluster M15. This speedy star got kicked out about 20 million years ago and is now zooming along at an incredible 550 km/s, fast enough that it's actually escaping our entire Galaxy! The researchers think this stellar ejection might have happened because of some cosmic game of pool - basically a three-body interaction involving one of those middle-sized black holes they've been trying to find!

There Could Be Life on Titan, But Not Very Much
The search for life in our Solar System, however primitive, past or present has typically focussed upon Mars and a select few moons of the outer Solar System. Saturn’s moon Titan for example has all the raw materials for life scattered across its surface, rivers and lakes of methane along with rock and sand containing water ice. There’s even a sprinkling of organic compounds too but according to a new study, Titan can probably only support a few kilograms of biomass overall, that’s just one cell per litre of water across Titan’s ocean.
