The concept of a black hole jet isn’t a new one, but we still have a lot to learn about the mixture of particles found in the vicinity of them. Through the use of ESA’s XMM-Newton Observatory, astronomers have been taking a look at a black hole in our galaxy and found some surprising results.
Billions of years ago when the Red Planet was young, it appears to have had a thick atmosphere that was warm enough to support oceans of liquid water – a critical ingredient for life. The animation shows how the surface of Mars might have appeared during this ancient clement period, beginning with a flyover of a Martian lake.
The Spitzer space telescope (which looks in infrared) and the massive Chilean Atacama Large Millimeter/submillimeter Array (ALMA) are both designed to look through the stuff to see what’s within. Here’s what they’ve spotted.
Imagine being able to watch three months’ worth of high-definition space video sequentially — maybe real-time coverage on the International Space Station, or getting to watch the Mars Reconnaissance Orbiter zoom across the Red Planet over and over again. Well, that’s how much science data MRO itself has sent back in 10 years of operations, NASA said.
With an annual cost of $30.8 million, the Keck Observatory costs $53.7 thousand for a single night’s worth of operation. It will cost the James Webb Space Telescope approximately $8.8 billion to reach orbit. And the Space Launch System that will carry the Orion capsule is expected to cost $38 billion.
Why should we be spending such a vast amount of money on astronomy? How is it useful and beneficial to society?
As you probably know, the Earth is rotating on its axis. This gives us day and night. Of course it’s impossible, but what would happen if the Earth stopped spinning? Remember, this isn’t possible, it can’t happen, so don’t worry.
Imagine you’re a space tourist wanting to blog about your experience. Too impatient to wait for the ride back to solid ground, you open up your laptop on the way home and post pictures and video of the experience just minutes after you were zooming through suborbital space.
The Sun is finally acting like it’s in solar maximum. Our Sun has emitted dozens of solar flares in since Oct. 23, 2013, with at least six big X-class flares. During 2013, there has been intermittent strong activity, but the activity since mid-October is really the first extended period of activity.
Take a ride on the Mercury express and see what MESSENGER sees in these two new videos! Each made from over 280 Narrow-Angle Camera (NAC) images taken at intervals of four seconds, the videos give us a first-class seat on a flight over some of the rugged, sun-scorched surfaces on Mercury’s southern hemisphere.
This NASA Hubble Space Telescope set of images reveals a never-before-seen set of six comet-like tailsradiating from a body in the asteroid belt, designated P/2013 P5.
In true Richard Branson flair, the founder of Virgin Galactic has a multimedia plan in place for when he and his adult children, Holly and Sam, take the first planned tourist spaceflight next year. Virgin Galactic and NBCUniversal signed a “multi-platform partnership” for the network’s affiliates to transmit the flight all over the place.
Two Russian cosmonauts clad in Orlan spacesuits are conducting an out-of-this-world handoff of the Olympic torch at the start of Saturday’s planned 6-hour spacewalk to perform maintenance on the International Space Station.
The Gravity field and steady-state Ocean Circulation Explorer (GOCE) satellite has been orbiting Earth in super-low orbits since 2009, mapping out variations in Earth’s gravity in extreme detail. But its fuel ran out in mid-October and the satellite began its slow descent towards Earth, being brought lower and lower by the effects of the atmosphere. Engineers predict it will re-enter completely and fall back to Earth sometime this weekend.
But no one can say for sure when or where the 1-ton satellite will fall.
I’m starting to get the chills about Comet ISON. I can’t help it. With practically every telescope turned the comet’s way fewer than three short weeks before perihelion, every week brings new images and developments. The latest pictures show a brand new tail feature emerging from the comet’s bulbous coma. For months, amateur and professional astronomers alike have watched ISON’s slowly growing dust tail that now stretches nearly half a degree or a full moon’s diameter. In the past two days, photos taken by amateur astronomers reveal what appears to be a nascent ion or gas tail. Damian Peach’s Nov. 6 image clearly shows two spindly streamers.
Stop what you’re doing, grab the nearest 3-D glasses (red/blue type) you have available and then pretend you’re hovering above Mars for a while. These are some of the latest images from the Mars Reconnaissance Orbiter, which has been cruising above the planet since 2006.
