Fireball meteor over Brazil may have come from another solar system - CNET
A small space rock that slammed into Earth's atmosphere and flamed out as a spectacular fireball over Brazil may have traveled from beyond our solar system to put on the bright display.
Brazil's Meteor Watch Network (Bramon) captured the so-called Earth-grazer meteor on Sunday evening over the southern part of the country. Two cameras in the network captured the meteoroid burning up in a brilliant streak painting its way across the night sky.
Chasing interstellar objects like Oumuamua may one day provide new insights into the nature of the universe, but collecting interstellar meteorites that make it to the ground might be a far easier way to go about it.
NASA Is On A Moonhunt.
To present the best information in a single view of Jupiter's moon Ganymede, a global image mosaic ... [+] was assembled, incorporating the best available imagery from NASA's Voyager 1 and 2 spacecraft and NASA's Galileo spacecraft. This image shows Ganymede centered at 200 west longitude. This mosaic (right) served as the base map for the geologic map of Ganymede (left).
What's the largest moon in the Solar System? Bigger than the planet Mercury and not much smaller than Mars, Ganymede is about to be explored by a NASA spacecraft that will next week begin an exciting extended mission.
2 new NASA robotic missions to investigate how Venus became solar system’s hottest planet |
NASA is returning to sizzling Venus, our closest yet perhaps most overlooked neighbor, after decades of exploring other worlds.
The space agency’s new administrator, Bill Nelson, announced two new robotic missions to the solar system’s hottest planet, during his first major address to employees Wednesday.
"These two sister missions both aim to understand how Venus became an inferno-like world capable of melting lead at the surface,” Nelson said.

NASA Selects 2 Missions to Study 'Lost Habitable' World of Venus
Venus hides a wealth of information that could help us better understand Earth and exoplanets. NASA's JPL is designing mission concepts to survive the planet's extreme temperatures and atmospheric pressure. This image is a composite of data from NASA's Magellan spacecraft and Pioneer Venus Orbiter.
Following a competitive, peer-review process, DAVINCI+ and VERITAS were chosen based on their potential scientific value and the feasibility of their development plans.
"Quark Star as Big as Our Solar System" | The Daily Galaxy
An enigma within a mystery revealed an explanation to the peculiar emission lines seen in a supernovae as bright as an entire galaxy – SN 2006gy, a hypernova or quark-nova (a hypothetical supernova that gives birth to a quark star instead of a neuron star) inside galaxy NGC 1260, some 250 million light-years away, first discovered on September 18, 2006- as well as an explanation for its previously unknown origin.
Superluminous supernovae are the most luminous explosions in the cosmos. SN 2006gy is one of the most studied such events, but researchers have been uncertain about its origin. Astrophysicists at Stockholm University have, together with Japanese colleagues, now discovered large amounts of iron in the superluminous supernova –among the brightest in the cosmos–through spectral lines that have never previously been seen either in supernovae or in other astrophysical
Volcanoes in the Solar System come in many varieties, shapes and sizes | The Canberra Times |
There are a range of different types of volcanoes on Earth, from the wide and short shield volcanoes of Hawaii to the steep, tall and explosive stratovolcanoes found at the edges of tectonic plates (think the kind of volcano that destroyed Pompeii).
On Earth, most of our volcanoes are driven by plate tectonics - the movement of large plates of the Earth's crust - where they collide or separate causing magma to be released from under the surface.
