Venus is often referred to as Earth's evil twin and NASA asked one of its scientists why that is. While the answer as to why Venus is thought of as Earth's twin may be better known, what makes our closest neighbor "evil" may not be. Venus is the second closest planet to the Sun at a distance of around 67 million... Read more...
NASA's retired Earth Radiation Budget Satellite (ERBS) is expected to reenter Earth's atmosphere after nearly four decades in space. For 21 of those years, ERBS actively investigated how Earth absorbed and radiated energy from the Sun. The Department of Defense has projected that the 5,400-pound satellite will... Read more...
A comet discovered in March of last year may not return to Earth for another 50,000 years, or ever. C/2022 E3 (ZTF) was spotted when it was already inside the orbit of Jupiter. The first month of 2023 will be filled with bright stars. In the first few hours after dark, the bright constellations Orion the hunter... Read more...
Chinese researchers believe they have discovered the origins of water in lunar soils. The team published their findings in the Proceedings of the National Academy of Sciences of the United States of America (PNAS). A joint research team from the National Space Science Center (NSSC) and the Institute of Geology and... Read more...
The crew on the International Space Station (ISS) has captured some fascinating images over the last year. From three CubeSats beginning their journey, to a decades-long eruption on Earth, the images are truly inspiring. As the International Space Station continues its scientific journey orbiting over 200 miles... Read more...
In order to celebrate the release of it's asteroid toolkit, the European Space Agency (ESA) has issued a challenge to find a mystery asteroid. The Christmas asteroid poses no threat to Earth, but the agency says it does not know much about 2015 RN35, which presents an opportunity for learning more about... Read more...
As NASA's Orion spacecraft began its journey back to Earth, it captured more awe-inspiring images, with our home planet finding a way to photo-bomb a few. Orion is set to make splashdown in the Pacific Ocean on Sunday, December 11, 2022. The Artemis I mission had a bit of a rough start, with several delays to its... Read more...
A NASA-funded team has created a new model that explains the scarcity of planets with masses between super-Earths and mini-Neptunes. The new model aims to explain two puzzling observations that continually appear among the more than 3,800 planetary systems cataloged to date. As scientists and astronomers... Read more...
A G1-class geomagnetic storm on November 3rd ripped a hole in Earth's magnetic field, resulting in an extremely-rare explosion of pink and purple auroras. The magnificent event was captured by Markus Varik of Tromso, Norway. Seeing stunning aurora lights after a geomagnetic storm is not anything unusual. Especially... Read more...
The Moon will be entering the Earth's shadow this month, creating a spectacular total lunar eclipse, called a "Blood Moon." If you miss catching this event while it's happening live, it will be another three years before another total lunar eclipse will occur. A lunar eclipse occurs when the Sun, Earth, and Moon...

Astronomers have discovered the closest-known black hole to Earth, at just 1600 light-years away. It is also the first clear detection of a dormant stellar-mass black hole in the Milky Way. Stellar-mass black holes typically weigh in at approximately five to 100 times the mass of our Sun. These types of black holes... Read more...
An international team used the Dark Energy Camera (DECam) to discover three new near-Earth asteroids (NEAs) hiding behind the glare of the Sun. One of the asteroids discovered is the largest near-Earth asteroid spotted in the last 8 years. It seems like new near-Earth asteroids are being discovered every other day... Read more...
A newly discovered asteroid, roughly the size of the world's tallest building, will make a near-Earth pass on November 1, 2022. The mammoth asteroid, called 2022 RM4, was discovered on September 12, 2022, by the Pan-STARRS 2 telescope in Hawaii. NASA recently flew a spacecraft into asteroid Dimorphos, in order to...

An astronaut onboard the International Space Station (ISS) took an incredible of image of a lightning strike while over Southeast Asia, and the Moon took the opportunity to photo bomb the picture. The image was captured last year by an unnamed member of the Expedition 66 crew. Astronauts aboard the ISS no doubt see... Read more...
A new study indicates that a giant tsunami caused by an asteroid impact played a large role in the extinction of many of the dinosaurs. The miles-wide asteroid that impacted Earth an estimated 66 million years ago took out nearly all the dinosaurs and about three-quarters of the planet's plant and animal species... Read more...
9/26/2022 Update As a reminder, Jupiter's closest pass to Earth is tonight, so don't miss the opportunity to see it! It is a busy night for space as the NASA DART mission is reaching its conclusion this evening as well. Original story below... Jupiter will be in opposition to the Sun later this month, presenting an... Read more...
NASA's DART mission is nearing its final destination later today, as the spacecraft will slam into asteroid Dimorphos in hopes of changing its speed and path. You will be able to follow along tonight as the space agency will be sharing a live feed from the spacecraft, as well as a post-impact press briefing. DART... Read more...
A new study by researchers at UC Riverside created detailed models on data from the solar system as it appears in modern day, as well alternatives to the solar system with a slightly different orbital path. One alternative solar system appeared to be effective in making Earth more habitable, by simply making Jupiter's... Read more...
An international team of researchers have discovered two super-Earth exoplanets, and one of them may be habitable. One of the planets is located at a distance from its star which potentially means it could hold liquid water on its surface. The vast majority of exoplanets discovered so far have not proven to be good... Read more...
"Diamond Rain" could be more prevalent on ice giants throughout the universe than previously thought. The new research has provided scientists with a more complete picture of how diamond rain forms on other planets. It could introduce a new way of fabricating nanodiamonds here on Earth. In a previous experiment... Read more...
The Earth just completed a full rotation in a little over a thousandth of a second shorter than its normal 24-hour rate. The record full spin occurred on June 29, 2022, and has some scientists concerned. Our planet has been spinning faster recently. Back in 2020, Earth saw its shortest month ever measured since the...

Data from NASA's Lunar Reconnaissance Orbiter (LRO) and computer modeling show shaded pits on the Moon always hover around 63 F (about 17 C). The pits and caves could provide a stable environment for lunar exploration when the surface could reach extreme temperatures. NASA's Artemis program is slated to put the... Read more...
