By measuring very precisely the motion of the Andromeda galaxy relative to the Milky Way, astronomers using the Hubble Space Telescope were able to determine in 2012 that the Milky Way and Andromeda are destined for a head-on collision in about 4 billion years.
It is very rare that a scientific experiment not only continues to be generally productive, but to yield cutting-edge results for 25 years. Yet, this ...
Our understanding of the processes that make real stars shine has not taken anything away from the attraction of the five-pointed star.
Scientists are not blind to the beauty of the world. When I see an image such as the one taken by the Hubble Space Telescope that was dubbed "The Rose," I believe that I am as capable to appreciate its exquisitely complex elegance as any artist.
Recently, the search for extraterrestrial life has started to gain significant momentum. Several factors have combined to advance the search for life to the level of a high-priority quest.
The discovery (if and when it happens) of extraterrestrial complex life will undoubtedly usher in a revolution that will rival the Copernican and Darwinian revolutions combined.
Hubble's scientific successor, the James Webb Space Telescope, will literally infuse new meaning into the phrase "the search for our origins."
It's truly refreshing that Sandra Bullock's character, Dr. Ryan Carter, is depicted in Gravity as an intelligent professional.
"The thing is you are prepared to do your job, but you are not prepared for the view around you. You know, what you see around you is just so magnificent it just kind of blows your mind, and the view of the earth is just incredible."
The shapes in the sand and the constellations in the sky become one, mirroring the tortuous path of human life in the dramatic Hubble images of outbursts that simultaneously mark stellar deaths and the promise for a new generation of stars, planets, and life.
Blunders are not only inevitable, they are an essential part of any innovative thinking process. If not for them, any creative enterprise might be wandering for much too long down too many blind alleys.
The goal is to use those so-called "Frontier Fields" to reveal populations of fainter galaxies, and to characterize the morphologies of distant star-forming galaxies.
The deep ocean is not the only place where we can marvel at the wonders of nature. The heavens are another such place, and the Hubble Space Telescope, in particular, has captured for us some images about which we can truly say that they are "out of this world."
When the Hubble Space Telescope was launched in 1990, the original idea was that it would operate for 10 years. That period was later extended to 15 years. Well, on April 24, Hubble celebrated 23 years since launch, and the telescope is going as strong as ever.
The question become particularly intriguing when we realize that astronomers now estimate that the Milky Way galaxy alone may harbor as many as 4.5 billion Earth-sized planets in the "habitable zones" around their host stars.
Almost everyone would agree that the image of the radio galaxy Hercules A, taken by the Karl G. Jansky Very Large Array radio telescope and the Hubble Space Telescope, is beautiful.
