  Washington DC (SPX) May 08, 2019 Detection of a supernova with an unusual chemical signature by a team of astronomers led by Carnegie's Juna Kollmeier - and including Carnegie's Nidia Morrell, Anthony Piro, Mark Phillips, and Josh Simon - may hold the key to solving the longstanding mystery that is the source of these violent explosions. Observations taken by the Magellan telescopes at Carnegie's Las Campanas Observatory in Chile were crucial to detecting the emission of hydrogen that makes this supernova, called ASASSN-18tb, so distin ... read more |

Discovered in 2004, Haumea is a dwarf planet located beyond Pluto's orbit in a region of the Solar System called the Kuiper Belt. Pluto was demoted from the category of fully fledged planets in 2006 because of the discovery of Haumea and other dwarf planets.
Haumea was officially recognized as a dwarf planet in 2008. Its ellipsoidal shape resembles that of the ball used in rugby or America ... more |

 Toronto, Canada (SPX) Apr 30, 2019 
The study of a tiny grain of stardust - older than our solar system - is shining new light on how planetary systems are formed.
The microbe-sized extraterrestrial particle, which originated from a nova explosion more than 4.5 billion years ago, was discovered inside a meteorite collected in Antarctica by the National Aeronautics and Space Administration (NASA).
Alongside planetary sc ... more |

The same winds that blanket Mars with dust can also blow that dust away. Catastrophic dust storms have the potential to end a mission, as with NASA's Opportunity rover. But far more often, passing winds cleared off the rover's solar panels and gave it an energy boost. Those dust clearings allowed Opportunity and its sister rover, Spirit, to survive for years beyond their 90-day expiration dates. ... more |

For more than a century, scientists have squabbled over how the Earth's moon formed. But researchers at Yale and in Japan say they may have the answer.
Many theorists believe a Mars-sized object slammed into the early Earth, and material dislodged from that collision formed the basis of the moon. When this idea was tested in computer simulations, it turned out that the moon would be made p ... more |

The Ozone Monitoring Instrument (OMI) aboard NASA's Aura satellite specializes in finding "fingerprints" - signatures of gases and particles that clutter the atmosphere. By measuring solar radiation reflected from Earth's surface and scattered by its atmosphere, the OMI team derives important information about aerosols such as dust and smoke and pollutants like nitrogen and sulfur dioxide.

The Double Asteroid Redirection Test (DART) - NASA's first mission to demonstrate a planetary defense technique - will get one chance to hit its target, the small moonlet in the binary asteroid system Didymos.
The asteroid poses no threat to Earth and is an ideal test target: measuring the change in how the smaller asteroid orbits about the larger asteroid in a binary system is much easier ... more |

The celestial phenomenon known as STEVE is likely caused by a combination of heating of charged particles in the atmosphere and energetic electrons like those that power the aurora, according to new research. In a new study, scientists found STEVE's source region in space and identified two mechanisms that cause it.
Last year, the obscure atmospheric lights became an internet sensation. Ty ... more |
