Juno just raced in Europa, making our best appearance in 20 years in the Ice World

Zoom / Our best images have been collected from Yoruba over two decades ago. On Thursday morning, NASA’s Juno spacecraft swooped 358 kilometers from the surface of Europa, the large, ice-covered moon orbiting Jupiter. This flyby will provide humanity with a closer look at Europe since the Galileo mission made several close flights more than …

Hubble discovers the protective shield that defends a pair of dwarf galaxies

credit: NASA For billions of years, the Milky Way’s largest satellite galaxy – the Large and Small Magellanic Clouds – has followed a perilous journey. Orbiting each other as they are pulled toward our galaxy, they begin to collapse, leaving trails of gaseous debris behind. Yet—to the confusion of astronomers—these dwarf galaxies remain intact, with …

Photographer captures Jupiter and its moons rising above a barn

Photographer Brennan Gilmore has taken advantage of Jupiter’s closest position to Earth in the last 59 years and captured a picture of the gas giant with its four moons in Galilee above a hangar roof. The image shows Jupiter plus its moons, left to right, Ganymede, Europa, Io and Callisto, taken on Monday, September 16 …

NASA has been a success but aims for bigger victories

Even for the agency that put the first humans on the moon, designed and flew the first reusable spacecraft and expanded the instruments of terrestrial and extraterrestrial space exploration, and subsequent knowledge of the universe, in myriad ways, NASA has pulled together a strong string of victories recently. On Monday evening, the world had a …

Artemis 1: A fire at NASA Kennedy gives the long-delayed moon mission its latest development

NASA in the middle To mitigate the destructive power of a powerful hurricane heading toward Florida. Tuesday emerged another dash of chaos, when a fire broke out inside the building that currently houses the agency’s Moonbound Artemis I rocket. Kennedy Space Center (KSC) Administrator Janet Petro told reporters Tuesday that NASA leaders are considering how …

The repetition of a fast radio burst with a strange magnetic field defies magnetic explanation

A frequent fast radio burst (FRB) with a changing polarized magnetic field has deepened the mystery of what produces these mysterious millisecond-long bursts of radio waves from deep space. Since their discovery in 2007, FRBs have been one of the most enduring mysteries in Astrophysics. It is extremely powerful, emitting the same amount of energy …

NASA’s Flying Telescope is nearing the end of its mission but leaves a powerful scientific legacy

Most telescopes here on Earth are stationary and fixed to one place, often in the desert or on top of a mountain. But NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) isn’t most telescopes. Sophia, which NASA partners with the German Space Agency (DLR), is a flying observatory. More specifically, it’s a Boeing 747SP with a …

Evidence of an asteroid collision that killed dinosaurs on the moon has been found

Asteroid impacts on the Moon millions of years ago are consistent with major space rock strikes here on Earth – including the massive impact that wiped out the non-floating dinosaurs. The discovery reveals that the main influences during prehistoric times on Earth were not isolated events. Instead, these asteroid strikes were accompanied by a series …
