Imagine hearing a sound that began its journey before our galaxy even existed. That is what astronomers are doing now. They are picking up faint signals that have travelled for more than 13 billion years to reach Earth. These signals come from a time when the universe was still very young, long before the Milky…
Astronomers have signalled the discovery of a planetary body roaming the Milky Way that is not gravitationally bound to the Sun or any other star. The entity is termed a free-floating planet, a class that embraces planetary mass bodies that are travelling in interstellar space independently. These bodies do not shine in a way that…
Among life’s most profound experiences is being able to witness the Milky Way stretching across the dark canvas of the sky. In fact, the stars, nebulae, and interstellar matter of our own Milky Way galaxy create a spectacle in space that fascinates both professional astronomers and amateur ‘star watchers’ in equal measure. For such viewing…
Pune: Two astronomers from Pune-based National Centre for Radio Astrophysics, using the powerful James Webb Space Telescope (JWST), have discovered what could be one of the earliest spiral galaxies ever detected, complete with clearly observable arms, just like our own Milky Way.It’s a surprising discovery, said astronomers Rashi Jain and Yogesh Wadadekar, who named the…
The early universe was once thought to be a quiet place where young galaxies grew slowly, gathered dust gradually and took long periods to form stars. New observations, however, show a much more active picture. One recently identified galaxy, located around 600 million years after the Big Bang, displays levels of warmth, brightness and star-forming…
The Milky Way, our home galaxy, is a vast and mysterious system brimming with stars, planets, dust, and cosmic wonders. For centuries, humans could only admire its hazy band across the night sky, but modern space technology has transformed our view. Thanks to NASA’s advanced observatories such as Hubble, Spitzer, Chandra, and newer missions, astronomers…
