Gamma-ray bursts that are longer than two seconds are caused by the detonation of a rapidly rotating massive star at the end of its life on the main sequence. Jets of particles and gamma radiation are emitted in opposite directions from the stellar core as the star collapses. In this model, a narrow beam of gamma rays is emitted, followed by a wider beam of gamma rays. The narrow beam for GRB 080319B was aimed almost precisely at the Earth, which made it the brightest gamma-ray burst observed...

The last U.S. spacecraft mission to Venus was in 1989 with the launch of Magellan. Even though Magellan spent the next five years radar mapping the surface and gathering high resolution gravity data, much remains a mystery about our so-called sister planet. Did Venus experience a run-a-way greenhouse effect at some point in its history? Why is the surface pressure 90 times greater on Venus then on Earth? Why is the planet so hot?

The bluer color in the latter part of the pulse indicates the presence of gamma rays with energies exceeding a billion electron volts (1 GeV).

Analyzing the Sun and its affects on climate is complicated by the fact that the amount of radiation arriving from the Sun is not constant. It varies from the average value of the total solar irradiance (TSI)--1,361 W/m2--on a daily basis. Variations in TSI are due to a balance between decreases caused by sunspots and increases caused by faculae, which are the bright areas that surround sunspots. The Sun's energy output varies with time, and Glory's TIM instrument will help measure those...

Aerosols are complex particles; they can occur in nature but can also be generated by humans. Black carbon, or soot, is generated from industrial pollution, traffic, outdoor fires, and household burning of coal and biomass fuels. Soot is a product of incomplete combustion, especially of coal, diesel fuels, biofuels and outdoor biomass burning. When soot absorbs sunlight, it heats the surrounding air and reduces the amount of sunlight reaching the ground. The heated air makes the atmosphere less...

One critical new area of aerosol research involves how the varied particles impact clouds. Clouds play an important role in regulating Earth's climate, and without aerosols, clouds could not exist. The introduction of a larger number of aerosols will modify cloud's natural properties, leading to clouds that are bigger, brighter, and longer lasting. Two time lapsed scenes with zooms to particle-level conceptual animations help to illustrate this concept. In a pristine environment, like the ocean...

Total solar irradiance (TSI) is the dominant driver of the Earth's climate. The global temperature of the Earth is almost completely determined by the balance between the intensity of the incident solar radiation and the response of the Earth's atmosphere via absorption, reflection, and re-radiation. Roughly 30 percent of the TSI that strikes the Earth is reflected back into space by clouds, atmospheric aerosols, snow, ice, desert sand, rooftops, and even ocean surf.

The X-Ray Telescope (XRT) aboard NASA's Swift satellite captured light echoes from a soft-gamma-ray repeater. These stellar remnants, which are thought to be highly magnetized neutron stars called magnetars, occasionally belt out a series of X- and gamma-ray flares. On Jan. 22, 2009, an object known as SGR J1550-5418 began its second and most intense round of outbursts since October 2008. In the following days, Swift's XRT captured what appears to be an expanding halo as X-rays from the...

Aerosols are complex particles; they can occur in nature but can also be generated by humans. One source of naturally-occurring aerosols is the ocean-wave activity which propels salt particles into the air. These particles then serve as cloud condensation nuclei and lead to cloud formation.

A planet twice the mass of Earth shepherds dust near its orbit into a circumstellar ring structure. Both the planet and the dust structure orbit the host star with a period of 5.2 years. Two regions of enhanced dust density lead and trail the planet, which causes periodic localized brightening. This simulation was computed using NASA GSFC's 420-processor Thunderhead cluster. Stark used the cluster to create a catalog of debris-disk structures caused by Earth-like planets. The catalog is...

A pulsar is a rapidly spinning and highly magnetized neutron star, the crushed core left behind when a massive sun explodes. Most were found through their pulses at radio wavelengths, which are thought to be caused by narrow, lighthouse-like beams emanating from the star's magnetic poles. When it comes to gamma-rays, pulsars are no longer lighthouses. A new class of gamma-ray-only pulsars shows that the gamma rays must form in a broader region than the lighthouse-like radio beam.

A pulsar is generally believed to be a rapidly rotating neutron star that emits pulses of radiation (such as x-rays and radio waves) at known regular intervals. A millisecond pulsar is one with a rotational period in the range of 1-10 milliseconds. When a pulsar is created in a supernova, is is born spinning, but slows down over millions of years. However, if the pulsar is in a binary system, the influx of material into its accretion disk may help the pulsar spin up to the millisecond range....

A millisecond pulsar is one with a rotational period in the range of 1-10 milliseconds. As the pulsar picks up speed through accretion, it distorts due to subtle changes in the crust. Such slight distortion is enough to produce gravitational waves. Material flowing onto the pulsar surface from its companion star tends to quicken the...
