There are those who believe that we made a huge mistake by not moving forward with advancing the NASA Space Shuttle Program or replacing it immediately with another manned-expedition project. This picture says in a nutshell what many of us feel – that the space shuttle represented more than just missions. It was a representation of our dreams as a country and the hopes of young men and women throughout America.

Few would argue that space is beautiful. On earth, we have beautiful things as well, including the iconic rose. When you combine the two, the results can be spectacular. Do you see it?
A new image taken by NJIT Distinguished Professor Philip R. Goode and the Big Bear Solar Observatory (BBSO) team is the most detailed sunspot photo yet. In September, the popular astronomy publication, Ciel et l’Espace will publish more photos of the Sun taken using BBSO’s new adaptive optics system.
Goode said that the images were achieved with the 1.6 m clear aperture, off-axis New Solar Telescope (NST) at BBSO. The telescope has a resolution covering about 50 miles on the Sun’s surface.
In the center is a dark sunspot, that is to say a colder zone, less brilliant than the rest of the solar surface. The temperature is around 3600 ° C. All around, the mosaic of small cells is called granulation (temperature: about 5800 ° C). On an average size of 1000 km, these cells are made of hot gas rising from inside the Sun.
A new discovery sheds light on the early stages of solar system formation as astronomers image a young brown dwarf in a close orbit with a nearby sun-like star. A team of astronomers and graduate students made the rare discovery using the NICI (Near-Infrared Coronagraphic Imager) and the 8-meter Gemini-South Telescope in Chile.
The distance between the sun-like star and its brown dwarf companion is what makes this discovery exciting. The 36 Jupiter-mass brown dwarf (PZ Tel B) and the sun-like star (PZ Tel A) are only 18 AUs (Astronomical Units) apart, similar to the distance between our sun and the planet Uranus.
Scientists have been monitoring and calculating the likelihood of a potentially disastrous asteroid collision with the Earth in the year 2182. The asteroid, (101955) 1999 RQ36, is only estimated to be a one-in-a-thousand chance that it will collide with the Earth, but as scientists have calculated the potential impacts through the year 2200, over half of the calculations point to the year 2182 for a collision.
The mathematics behind the calculations come by using two different models, the Monte Carlo Method and line of variations sampling. Using these models, VIs (Virtual Impactors) have been searched. VIs are sets of uncertainties that would lead to collisions with the Earth, two of which appear in 2182 with over half the chance of an impact.
The asteroid is part of a group of Potentially Hazardous Asteroids (PHA), which all have the possibility of colliding with the Earth and causing damage because of the proximity of their orbits. The asteroid in question was discovered in 1999 and has roughly 560 meters in diameter.
For the past three years, scientists at NASA have been compiling data on over 100 computers to create this comprehensive map of Mars. The collection of data spans about 40 years worth of space exploration, from the Viking orbiters to the current Mars Reconnaissance Orbiter.
