Blazar Hunting - 1
Nearly 10 billion years ago the black hole at the center of a distant galaxy produced a powerful outburst and light from this blast began arriving at Earth in 2012 Astronomers using data from NASAs Fermi Gammaray Space Telescope and other space and groundbased observatories have shown that a recordbreaking neutrino seen around the same time likely was born in the same event

Destination Asteroid - 5

Destination Asteroid - 5
Not far from Earth dark bodies of rock circle the sun in lonely orbits These near Earth objects or NEOs are asteroids found outside the traditional belt between Mars and Jupiter Protected from the gravitational tugs and tumbles that affect objects found closer to the gas giant these asteroids may contain clues about the origins of the solar system

Faint Young Sun Paradox - 6

Faint Young Sun Paradox - 6
Some 4 billion years ago the sun shone with only about threequarters the brightness we see today Powerful solar explosions may have provided the crucial energy needed to warm Earth despite the suns faintness The eruptions also may have furnished the energy needed to turn simple molecules into the complex molecules such as RNA and DNA that were necessary for life

Hurricane Modeling - 7

Hurricane Modeling - 7
Improving hurricane forecasts means testing historical storms with todays sophisticated models and supercomputers NASA and NOAA work together in gathering ground and satellite observations as well as experimenting with forecast models As a result of this collaboration model resolution has increased and scientists are discovering more about the processes that occur within these storms

Jupiters Climate - 8

Jupiters Climate - 8
When scientists look at Jupiters upper atmosphere in infrared light they see the region above the equator heating and cooling over a roughly fouryear cycle They dub this Jovian climate pattern the quasiquadrennial oscillation or QQO and it has a sibling on Earthnbspa twoyear temperature cycle accompanied by a reversal of the equatorial jet stream

Life of the Monsoon - 10

Life of the Monsoon - 10
The monsoon is a seasonal rain and wind pattern that NASA satellites and models are allowing us to see as never before Monsoon rains provide reservoirs of water that support the natural environment by replenishing aquifers However too much rainfall routinely causes disasters including flooding of the major rivers and landslides in areas of steep topography
