Halley’s Comet To Leave Orionids Meteor Shower Today

Halley’s Comet is one of the most popular meteors that pass near the Earth, and it has been doing so for centuries. However, because it is only visible every 75 years, do not expect to get a glimpse of it more than twice in an entire lifetime. However, a report says that aside from the arrival of the actual meteor, …

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 …

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 …

Asteroid 2014: Cosmic Monster Missed Earth This Morning

A couple million miles may not sound like much of a “close call” with an asteroid. But compare it to the vast and empty light years upon light years surrounding this oxygenated rock ball we ride around on in infinite space, and 1.6 million miles isn’t much wiggle room between us and a structure racing past at 27,000 miles per …

Yet Another Early-Universe Galaxy Has Been Spotted

Astronomers this week revealed that yet another galaxy from the very early universe has been spotted. The galaxy, dubbed Abell2744_Y1, is estimated to have existed just 650 million years after the big bang, which took place 13.8 billion years ago. The object was spotted during a survey of the Abell 2744 galaxy cluster using the Hubble and Spitzer space telescopes. …

“Wobbly” Planet Spotted in Binary Star System

NASA this week revealed that the Kepler Space Telescope has spotted a planet with a very erratic orbit. The planet, named Kepler-413b, orbits around a pair of stars and performs what astronomers are describing as a wobble as its spins. The planet’s binary system is located 2,300 light-years from our system and contains two dwarf stars, one orange and one …

New Planets Found Among Star Cluster

Astronomers this week have announced the discovery of three planets found within the Messier 67 star cluster. The finding is significant because planets have rarely found orbiting stars that are part of star clusters. The new research shows that planets may actually be just as common within star clusters as they are throughout the rest of the galaxy. “These new …
