It is as inevitable as the rising of the Sun and the turning of the tides. Someday another large rock from space will crash into the Earth. It has happened for billions of years in the past and will continue to happen for billions of years into the future. So far humanity has been lucky, as we have not had to face such a catastrophic threat. But if we are to survive on this planet for the long term, we will have to come to terms with the reality of hazardous asteroids and prepare ourselves.

Artemis 2 crew begins 1st moon mission training in 50 years
Newly divulged details about the Artemis 2 moon crew's include mission milestones and a simulated docking exercise planned in Earth orbit before flying to the moon.
Zombie white dwarf fed on neighbor star until bursting in a thermonuclear explosion
Astronomers have made the first detection of a supernova in radio waves, finding that an exploding white dwarf star was feeding from a companion star like a cosmic vampire before it blew.
Life Probably Didn't Have a Hand in Creating Organic Deposits on the Surface of Mars
At this very moment, eleven robotic missions are exploring Mars, a combination of orbiters, landers, rovers, and one aerial vehicle (the Ingenuity helicopter). Like their predecessors, these missions are studying Mars’ atmosphere, surface, and subsurface to learn more about its past and evolution, including how it went from a once warmer and wetter environment to the freezing, dusty, and extremely dry planet we see today. In addition, these missions are looking for evidence of past life on Mars and perhaps learning if and where it might still exist today.
Volcanoes may carpet surface of newfound Earth-size exoplanet
A newfound exoplanet that lies 90 light-years from Earth may be studded with active volcanoes, whose emissions could sustain an atmosphere.
Violent origins of gravitational waves probed by new telescope array
The new BlackGEM array will hunt for black hole mergers and neutron star collisions, cataclysmic events that generate ripples in space-time known as gravitational waves.
Kathy Lueders Was NASA's Top Human Spaceflight Official. Now She Works for SpaceX
Another of NASA’s top human spaceflight officials has joined SpaceX. Kathy Leuders, the former associate administrator for NASA’s Space Operations Mission Directorate, retired from NASA on May 1 after 31 years of service. But this week, CNBC reports that Lueders has joined SpaceX at the company’s Starbase facility in Texas. She follows Bill Gerstenmaier, who retired from NASA in 2020 and became a senior executive at SpaceX as build and flight reliability vice president.
'Crater' is an old-fashioned kids' sci-fi flick with out-of-this-world charm (review)
A review of Disney Plus's enjoyable new Young Adult sci-fi adventure movie, "Crater."
Astronomers Have a New Way to Measure the Expansion of the Universe
The cosmos is expanding at an ever-increasing rate. This cosmic acceleration is caused by dark energy, and it is a central aspect of the evolution of our universe. The rate of cosmic expansion can be expressed by a cosmological constant, commonly known as the Hubble constant, or Hubble parameter. But while astronomers generally agree this Hubble parameter exists, there is some disagreement as to its value.
Our oceans are in hot water
Adding to the grim list of record ice losses, record air temperatures and record droughts, which have all hit the headlines recently, the temperature of the surface waters of our oceans is also at an all-time high. With an El Niño looming, concerns are that we will soon be facing even worse extremes. Satellites orbiting overhead are being used to carefully track the patterns that lead up to El Niño to further understand and predict the consequences of this cyclic phenomenon against the backdrop of climate change.
Could the floating islands in 'The Legend of Zelda: Tears of the Kingdom' exist?
The latest entry in the Zelda series features floating islands high above the lands of Hyrule. But can we find these features on Earth, or alien planets?
An Innovative Heat Shield That Doesn’t Need to Be Replaced Between Missions
A revolution in space manufacturing is coming. Enabled by cheaper launch costs, companies are scrambling to take advantage of easier access to the benefits space offers as a manufacturing environment. These include a constant vacuum, near absolute zero temperatures, and a lack of any significant gravity. These features would enable easier processing and manufacturing of hundreds of products, from pharmaceuticals to metal alloys. The tricky part is getting them back down to Earth, where they can be used.
Powerful solar flare erupts from hidden sunspot sparking widespread radio blackouts (video)
The explosive solar flare erupted from a hidden sunspot on May 16 at 12:43 pm EDT (1643 GMT) triggering widespread radio blackouts.
Building telescopes on the moon could transform astronomy – and it's becoming an achievable goal
Lunar exploration is undergoing a renaissance. Dozens of missions, organized by multiple space agencies – and increasingly by commercial companies – are set to visit the moon by the end of this decade.
Capturing the Chromosphere in Australia's 2023 Hybrid Solar Eclipse
I traveled to Lake Turkana in Kenya in 2013 to observe just 11 seconds of totality during a hybrid solar eclipse. During this uncommon event, the apparent diameters of the […]
Radiation belt seen beyond our solar system for the 1st time
The radiation belt around the ultracool dwarf star, located around 19 light-years from Earth, is doubled-lobed like the radiation belts around Jupiter — but it's 10 million times brighter.
