Peeking beyond our own celestial neighborhood, there's a vibrant galaxy that astronomers can't get enough of – the Triangulum Galaxy, or M33. Although it pales in popularity to its more renowned counterparts like the Milky Way and Andromeda, the Triangulum Galaxy boasts a fascinating story and a unique charm that sets it apart.
The Triangulum, as third-largest in the Local Group, is hardly a shy neighbor – it's brimming with gas and dust, the raw material for fresh stars. Recently, Hubble Space Telescope snapped a mesmerizing image of this wondrous phenomenon, capturing approximately 25 million stars in the lens. This eyebrow-raising photograph isn't just a pretty picture – it offers scientists valuable insights into the composition of the Triangulum Galaxy, as well as the Milky Way.
The composite image, stitched together from 54 photographs taken between 2017 and 2018, reveals the galaxy's grand scale: approximately 60,000 light-years across, with around 40 billion stars within its bounds. Compared to our very own Milky Way, which boasts hundreds of billions of stars and measures 100,000 light-years wide, the Triangulum galaxy is a modest constellation.
But don't let its size fool you – the Triangulum Galaxy is far from quiet. This stargazing dynamo undergoes star formation approximately ten times more intensely than its neighbor, Andromeda. Each year, a shimmering new sun-sized star emerges from the gas and dust clouds teeming within the galaxy – a pace that astronomers find hypnotic on a cosmic scale.
For many years, researchers have puzzled over the trajectory of the Triangulum Galaxy. In 2019, however, new data provided by the Gaia space telescope shed light on the galaxy's future. The study revealed that, contrary to earlier models, M33 is not orbiting M31 – instead, it's hurtling towards a close encounter with our galaxy. And here's where things get even more intriguing: while M31 and the Triangulum Galaxy are approaching each other, M33 is heading straight for a collision with the Milky Way.
So, what does this mean for our home galaxy? Well, while this clash of titans is still light-years away, it's estimated to happen in hundreds of millions – or even several billions – of years from now. For now, we can marvel at the breathtaking image of the Triangulum Galaxy, which offers us a tantalizing glimpse of the cosmos unfolding beyond our sight.
Hubble's stunning portrait of the Triangulum Galaxy is available to examine in detail through the European Space Agency's zoom tool. Dive in, and prepare to be awestruck.
