APOD- Astronomy Picture of the Day
Have you ever seen a 9-gigapixel map of the Milky Way Galaxy? The jaw-dropping image contains around 84 million stars and it’s unlike anything I’ve ever seen. The original image has 24.6 gigabytes. How would I define it? COSMIC LOVE. This is j…
Traveling above Jupiter at more than 130,000 miles per hour, NASA's $1 billion Juno probe took its ninth set of stunning flyby images. But the sun slipped between the giant planet and Earth for more than a week, blocking the spacecraft fr…
A recent observation of the red giant—the largest in the constellation Scorpio—shows that from its cosmic depths, the star is expelling unknown matter as it approaches the end of its life. In the insides of the star Antares lies a powerf…
When you spend almost more than $1 billion on a beautiful spacecraft, it can be a very nervous wait to see if everything actually pays off. But if and when it does, the results can be rather glorious. And NASA’s Juno spacecraft has just pa…
In 1995, astronomers pointed the Hubble Telescope toward a seemingly empty spot in the sky. Because the telescope was purposely directed far away from the glare produced by stars in the Milky Way, any source of light in the resulting view had…
Venera was a series of satellites launched by the Soviet Union in the 1970s and 1980s to study Venus’ environment. It was also the program aimed at returning the first images of the surface of another planet. Over the course of the program, th…
As an astrophysicist, I am always struck by the fact that even the wildest science-fiction stories tend to be distinctly human in character. No matter how exotic the locale or how unusual the scientific concepts, most science fiction end…
An international team of astronomers from Chile and Germany has managed to capture an image of unprecedented detail of another star — that isn’t the Sun — the red supergiant star Antares. The team has also made the first map of the velocities of …
According to experts, our Sun is tilted by about 6 degrees compared to the sun’s equator. The reason behind this has remained an astronomical mystery for decades. Now, experts believe they’ve finally found an answer: Planet Nine. Elizabeth Bail…
The Hubble Space Telescope has spotted the farthest star ever seen! A lucky alignment has revealed a single source of light in the first billion years after the big bang. The newly detected star is so far away that its light has taken 12.9 bil…
