Astronomers Find Sun’s ‘Long-Lost Brother,’ Pave Way for Family Reunion

AUSTIN, Texas — A team of researchers led by astronomer Ivan Ramirez of The University of Texas at Austin has identified the first “sibling” of the sun — a star almost certainly born from the same cloud of gas and dust as our star. Ramirez’s methods will help astronomers find other solar siblings, which could lead to an understanding of how and where our sun formed, and how our solar system became hospitable for life. The work appears in the June 1 issue of The Astrophysical Journal.

“We want to know where we were born,” Ramirez said. “If we can figure out in what part of the galaxy the sun formed, we can constrain conditions on the early solar system. That could help us understand why we are here.” (more…)

‘Standing on a comet’: Rosetta mission will contribute to space weather research

ANN ARBOR — A comet-bound spacecraft that’s been in sleep mode for more than two years is scheduled to wake up on the morning of Jan. 20—beginning the home stretch of its decade-long journey to a mile-wide ball of rock, dust and ice.

If all goes as planned, Rosetta—a European Space Agency-led mission that involves University of Michigan engineers and scientists—will be the first craft to actually land on a comet as well as track it for an extended period of time. (more…)

Solar tsunami used to measure Sun’s magnetic field

A solar tsunami observed by NASA’s Solar Dynamics Observatory (SDO) and the Japanese Hinode spacecraft has been used to provide the first accurate estimates of the Sun’s magnetic field.

Solar tsunamis are produced by enormous explosions in the Sun’s atmosphere called coronal mass ejections (CMEs). As the CME travels out into space, the tsunami travels across the Sun at speeds of up to 1000 kilometres per second.

Similar to tsunamis on Earth, the shape of solar tsunamis is changed by the environment through which they move. Just as sound travels faster in water than in air, solar tsunamis have a higher speed in regions of stronger magnetic field. This unique feature allowed the team, led by researchers from UCL’s Mullard Space Science Laboratory, to measure the Sun’s magnetic field. The results are outlined in a paper soon to be published in the journal Solar Physics. (more…)

Cosmochemist discovers potential solution to meteorite mystery

Chondrules may have formed from high-pressure collisions in early solar system

At issue is how numerous small, glassy spherules had become embedded within specimens of the largest class of meteorites—the chondrites. British mineralogist Henry Sorby first described these spherules, called chondrules, in 1877. Sorby suggested that they might be “droplets of fiery rain” which somehow condensed out of the cloud of gas and dust that formed the solar system 4.5 billion years ago. (more…)

Within ‘Habitable Zone,’ More Planets than We Knew

The number of known places in our galaxy theoretically hospitable to life may be significantly greater than previously thought, according to new research.

Researchers with Planet Hunters are reporting the discovery of a Jupiter-sized planet in the so-called “habitable zone” of a star similar to Earth’s sun, as well as the identification of 15 new candidate planets also orbiting within their star’s habitable zone. (more…)
