NASA's Radar System Recorded Two Near-Earth Asteroids

These observations were made using the Goldstone Solar System Radar. The radar system transmits radio waves to the asteroids and captures the reflected signals, enabling scientists to analyze their orbits, shapes, and surface details.

Astronomers Discover Young Earth-Sized Exoplanet With the 'Lava Hemisphere'

The planet is the closest Earth-sized exoplanet to our solar system this young, believed to be less than 500 million years old. HD 63433 d orbits a Sun-like star, sharing similarities with our own solar system.

A Massive Coronal Hole In the Sun's Surface Is Blasting Solar Wind Right at Earth

This phenomenon occurs as part of the Sun's natural activity cycle. While the Sun experiences periods of heightened solar activity, including sunspots or solar flares, it eventually reaches a peak known as solar maximum.

Supernova's Impact on Earth's Ozone Layer Revealed in a New Study

Simulations have revealed that a gamma-ray burst within our Milky Way could obliterate the stratospheric ozone layer for several years, causing extensive species extinction and posing significant threats to humanity.

NASA Astronauts' Tool Bag Becomes a Bright Satellite in Earth's Orbit

Currently orbiting at altitudes ranging from 415 to 416 kilometers, it is slowly descending. Eventually, it will re-enter the Earth's atmosphere, where it is anticipated to disintegrate.

Space

New Study Suggests That Earth Harbors Remnants of a Moon-Forming Protoplanet

These continent-sized anomalies, known as large low-velocity provinces (LLVPs), have long puzzled scientists due to their higher density and temperature compared to the surrounding mantle.

Digital Libraries of Earth's Knowledge to Be Scattered Across the Solar System for Eternity

AMF's ambitious plan is to place these time capsules, or "Arch libraries," in various locations across the solar system, including orbiting Earth and on the Moon. These repositories are designed to act as backups of Earth's knowledge and biology.

NASA Calculates Potential Earth Impact Date for Asteroid Bennu

Thankfully, the likelihood of such an event is estimated at around 1 in 2,700, according to a 2021 study. However, NASA remains vigilant, given the catastrophic consequences if it were to occur.

NASA Confirms Summer 2023 as the Hottest on Record

NASA's temperature record, known as GISTEMP, is compiled from surface air temperature data collected from thousands of meteorological stations worldwide, along with sea surface temperature data from ship- and buoy-based instruments.

NASA Shares a New Stunning Image of Earth Taken by the NOAA-21 Satellite

As noted, the images of the Earth that make up this mosaic and several close-ups were captured on December 5 and 6 using an instrument called the Visible Infrared Imaging Radiometer Suite (VIIRS) aboard the NOAA-21 imaging satellite.

Space

Astronomers Discover a Huge Planet Killer Asteroid

Over time, the movement of this asteroid will sync with that of the Earth, and it will cross much closer by, but it will happen centuries into the future. Any asteroid over 1km in size is considered a planet killer and enough to trigger a mass extinction event on Earth.

Astronomers Discover Closest Known Black Hole to Earth

A team of astronomers has discovered the closest known black hole to Earth using data from the Gaia spacecraft. They did it by observing the Sun-like star moving in unexpected ways caused by the gravity of an unseen massive object.

Two Large Asteroids Will Fly Past Earth This Weekend

Two large asteroids the size of a multi-story building will brush past our planet later this week. According to NASA, the space bodies will approach the Earth on July 29 and 30.

NASA's Lucy Spacecraft Captured Lunar Eclipse From Space

Over the course of about three hours, the spacecraft made 86 1-millisecond exposures. They were then sent back to Earth to be combined into a video. In the resulting video, the Earth and its satellite can be seen about 360,000 km apart.
