A Good Time to Observe Dwarf Planet Ceres
On March 21, we have a great opportunity to observe the dwarf planet Ceres. It will be at opposition, which means it will reach the highest point in the sky at around midnight and opposite to the Sun. At the same time Ceres will be closest to the Earth (perigee) at a distance of 1.59 AU. At this time it will be the brightest, with an absolute magnitude of 6.9. Look in the constellation of Coma Berenices with binoculars or a telescope.
Mimas and Iapetus, Two Odd Moons of Saturn
Saturn has a lot of moons. Two of them are really odd, and bear a striking resemblance to the Death Star from the Star Wars movies. Mimas has a crater of approximately the same scale as the one on the Death Star. Iapetus also has large craters, but the resemblance lies in its equatorial ridge.
The Top 10 Photographs of Celestial Objects
NASA has provided us with stunning photos over the years, featuring everything from stars and planets to nebulae and even distant galaxies, using telescopes here at home as well as probes orbiting our planet and exploring distant corners of the solar system. NASA uses a combination of both visible and invisible wavelengths of light to create images that we can enjoy so we have at least a small idea of what is waiting for us out in the cosmos. With that in mind, here are our top 10 photographs of celestial objects. 1. Jupiter Abyss (https://apod.nasa.gov/apod/ap190610.html) We’re all familiar with the elaborate cloud formations and the big Red Spot that…
Why Did Lunar Outpost Design Small Rovers for the Moon?
It's been a long time since we've sent people to the moon. The last human being set foot on our satellite in 1972 and though China has sent probes to the dark side of the Moon, no humans have visited it in decades. In spite of this, many countries are still looking up into the night sky and wonder if the moon has more to offer. One company is working on exploring that potential in the future. Why is Lunar Outpost designing small rovers for use on the moon?
Exciting Future Uses of Textiles in Space
When we think about space-age technology and exploring the Cosmos, we usually think of metals, foils and ceramics. But what about textiles? As many NASA engineers can tell you, textiles have always been an unsung hero in the world of material science. But if the future of space exploration pans out the way engineers expect, humanity’s status as a spacefaring species will see the inclusion of — and even come to depend on — advanced new types of fabrics, textiles and membranes. Here’s a preview. Rovers, Capsules and Other Vehicles When it comes to building something, you can generally choose materials that provide low weight or durability — usually not…
NASA Will Soon Decide If Changing Juno’s Course is Best
Jupiter is named after the king of the Roman gods, and with its massive size, it definitely holds the title of king of the Solar System. NASA's Juno spacecraft entered orbit around the gas giant in July of 2016. Due to a problem with the craft's propulsion system, NASA is currently debating whether changing Juno's course is the best option. What is Juno looking for out there among the stars?
How NASA’s Juno Mission to Jupiter Works [Infographic]
Recently, on August 5, 2011, NASA launched a new space probe, called Juno, headed towards Jupiter. When it reaches its destination the spacecraft will be placed in a polar orbit in order to study the planet's composition, gravity field, magnetic field, polar magnetosphere, and the deep winds of its atmosphere.
The Solar System To Scale [Infographic]
The following is a huge infographic showing the true scale of the solar system with all its planets, minor bodies and the most famous probes we have sent out into deep space. Scientists measure distances in our solar system in astronomical units (AU).
Saturn’s Moon Mimas Looks Like Pac-Man In Infrared
In an earlier article we have showed you how Saturn's moon Mimas totally looks like the Death Star from the Star Wars movies. Now it seems that Mimas also looks like Pac-Man from the 1980s video game when seen in infrared.
Astronomy Picture of the Week – The Rings of Saturn
This picture of Saturn’s rings in its natural colors has been taken by the Cassini probe from an angle impossible to get from Earth. We can see a huge gap in Saturn’s rings. This is caused by the planet obscuring the Sun’s light. Since the rings do not emit light on their own, a lack of sunlight would mean no reflected light, and thus they would remain dark. The rings are also projecting a shade on the planet near the equator for similar reasons, except here the roles are reversed. Saturn’s Rings by Cassini. Image credits: NASA/ESA
