Microscopic particles of stardust, known as “pre-solar grains,” have been found in meteoritic material on Earth. Researchers are investigating whether these particles may have formed in classical novae explosions, ejecting stellar material in the form of gas and dust into the space between stars in the galaxy, eventually to be recycled in the creation of our solar system.
The Moon will pass in front of the Sun on 9 March 2016 UT, casting its shadow over much of Southeast Asia. The path of totality, in which all of the Sun’s bright face is blocked by the Moon, is nearly 100 miles wide as it crosses Indonesia, while the partial phases can be seen from East Asia, Australia and the Pacific Ocean. Here is our detailed guide.
If you left it too late to book your Indonesian flight to view the total solar eclipse on the morning of Wednesday, 9 March (UT), don’t despair — put away your passport, sit back and enjoy the spectacle online, courtesy of Exploratorium and NASA TV. For virtual eclipse viewers in the UK, the event starts at 1am GMT on 9 March.
As the Moon slowly covers the face of the Sun on the morning of 9 March, a team of NASA scientists in Indonesia will be anxiously awaiting the start of totality. They plan to take 59 exposures of the Sun in just over three minutes, capturing data on the corona — the innermost parts of the Sun’s volatile, superhot atmosphere.
Scientists have long been puzzled about what makes Mercury’s surface so dark. The innermost planet reflects much less sunlight than the Moon, a body on which surface darkness is controlled by the abundance of iron-rich minerals. These are known to be rare at Mercury’s surface, so what is the “darkening agent” there?
This planetary nebula is known as Kohoutek 4-55 (or K 4-55). It is one of a series of planetary nebulae that were named after their discoverer, Czech astronomer Luboš Kohoutek. Such a nebula is formed from material in the outer layers of a red giant star that are expelled into interstellar space when the star is in the late stages of its life.
Peering deep into the early universe, this picturesque parallel field observation from the NASA/ESA Hubble Space Telescope reveals thousands of colourful galaxies swimming in the inky blackness of space in the constellation Sculptor. This spectacular skyscape was captured during the study of the giant galaxy cluster Abell 2744, otherwise known as Pandora’s Box.
University of Chicago scientists have discovered evidence in a meteorite that a rare element, curium, was present during the formation of the solar system. This finding ends a 35-year-old debate on the possible presence of curium in the early solar system, and plays a crucial role in reassessing models of stellar evolution and synthesis of elements in stars.
If you haven’t done so already, now is the time to ensure that your telescope is clean and collimated (aligned) to deliver the sharpest images of planet Jupiter at its best. We tell you the optimal UK times to view the largest planet’s Great Red Spot and multiple shadow transits from its Galilean moons.
