Annie Jump Cannon Gets Google Doodle On 151st Birthday

Annie Jump Cannon is the subject of a doodle today on Google’s homepage, as the search giant celebrates her 151st birthday. Cannon was an astronomer whose work was considered instrumental in the development of contemporary stellar classification. She, along with Edward C. Pickering, is credited with the creation of the Harvard Classification Scheme. This is said to be the first …

Hubble Space Telescope: Deep Field Image Brightened With Ultraviolet Light

The Hubble Ultra Deep Field (HUDF) is one of the most iconic and impressive images ever taken of deep space. The image, taken of a tiny section of the southern sky, shows thousands of galaxies, putting the vastness of space into perspective for humans. Now astronomers have improved upon this classic image, adding a wider range of colors to the …

Ganymede Sea Could Be Layered and Harbor Life

For decades now Jupiter’s moon Ganymede has been one of the more interesting objects in our solar system. The moon is one of the few that is known to have a large ocean beneath an icy layer, leading to speculation that primitive life may have evolved somewhere inside. This week astronomers have announced a discovery that increases the likelihood that …

Mars, Earth, And Sun All Set To Form Cosmic Alignment Called An ‘Opposition’

A rare astronomical event that takes place about every 26 months is set to happen on Tuesday, April 8th. Dubbed an “Opposition of Mars”, this spacial phenomenon involves the alignment of Mars with the Earth every 778 days. On this day, Mars, Earth, and the sun form a straight line. Since the Earth is closer than Mars is to the …

Moon Water May Not Be As Abundant As First Thought

In the latest twist surrounding the composition of the moon, scientists have discovered the possibility of the Earth and moon sharing the same source of water. A scientific paper entitled The Lunar Apatite Paradox contains findings of a new study that a common method for approximating the water content in lunar rocks could be flawed. Apatite is a type of …

Ring System Spotted Around Asteroid

Astronomers today revealed that an asteroid in the outer solar system has been confirmed to have its own Saturn-like ring system. The new findings have been published today in the journal Nature. The asteroid, named Chariklo, is a minor planet that orbits the sun between Saturn and Uranus. The object is also classified as a “centaur,” one of the many …

Moon Craters Mapped by Amateurs as Well as the Pros

CosmoQuest, a collective of amateur astronomers that identify and map craters on various space objects, including the moon, has gotten so adept in their studies that their data has been used in scientific research and at times published. Stuart Robbins, a research scientist at the University of Colorado’s Laboratory for Atmospheric and Space Physics who led a comparative study between …

Largest Yellow Star Yet Seen Spotted in Binary System

Astronomers this week revealed that they have spotted the largest yellow star ever seen. The object is more than 1300 times the diameter of our Sun and is also one million times brighter. It is also one of the ten largest stars ever discovered. The new observations are to be published in the journal Astronomy & Physics. The star is …

No “Planet X” Found in WISE Data

For decades before Pluto, Eris, and other distant objects in our solar system were discovered, astronomers had posited that there must be another planet beyond Neptune that would make observed orbital calculations for Neptune and Uranus add up. This planet was dubbed “Planet X” and was searched for extensively during the late 19th century. The search was largely abandoned when …

Distant Black Hole Spin Measured by Astronomers

Astronomers this week revealed that the spin of a very distant black hole has been directly measured. The new measurement is part of a new report published this week in the journal Nature and should help cosmologists further investigate the characteristics and evolution of black holes. The spin of black hole/quasar RX J1131-1231 was measured by University of Michigan astronomer …

Huge Weather Explosions Observed on Venus

Researchers this week announced that they have uncovered a striking phenomenon on the planet Venus. Using the European Space Agency’s (ESA) Venus Express spacecraft, scientists have observed giant weather explosions coming from the top of Venus’ atmosphere. The explosions are called hot flow anomalies and the ones seen coming off Venus are frequent and often larger than the planet itself. …

New Research Reveals Supernova Secrets

Supernovae seem easy enough to understand. Stars age, using up all of their fusion fuel and burst in a fiery display that helps to create the wide variety of elements seen throughout the universe. The trouble is, astronomers don’t yet actually understand the fine details that well. Today astronomers got a bit closer to unravelling the mysteries of these stellar …
