Today’s Current Affairs: Hubble Space Telescope Captures Stunning Image of Triple Star System
In the world of astronomy, the Hubble Space Telescope continues to amaze us with its latest image release of the triple star system HP Tau, HP Tau G2, and HP Tau G3. These young stars, with HP Tau only 10 million years old, are a sight to behold 550 light years away in the Taurus constellation.
Despite the growing excitement around the James Webb Space Telescope, Hubble reminds us of its historical impact on our understanding of the Universe since its launch in 1990. With its 2.4m mirror, Hubble has provided us with breathtaking views of celestial objects, like the reflection nebula captured in this latest image.
As we marvel at the beauty of this triple star system, we are reminded of the ongoing exploration of protoplanetary disks and the potential for new discoveries about the formation of planetary systems. Hubble’s legacy continues to inspire and educate us about the wonders of the cosmos.

What has Hubble Space Telescope recently captured an image of?
Hubble recently captured an image of the triple star system HP Tau, HP Tau G2, and HP Tau G3.
When was Hubble Space Telescope launched and how has it revolutionized our understanding of the Universe?
Hubble was launched in 1990 and since then, it has revolutionized our understanding of the Universe by providing stunning views of objects across the cosmos from its orbit around Earth.
What is a reflection nebula and what characteristic color do they have?
A reflection nebula is made up of interstellar dust that reflects light from nearby stars. They have a characteristic blue hue due to the reflective properties of the dust.
What are T Tau stars and how are they identified?
T Tau stars are a type of variable star that are less than 10 million years old. They are identified by studies of their optical variability and strong lines in their spectra from the chromosphere.
Why does the amount of light emitted by HP Tau vary with time?
The amount of light emitted by HP Tau varies with time because of its young nature. It may experience regular and sometimes random fluctuations possibly due to material dumping onto the star from an accretion disk.
What is the significance of studying protoplanetary disks around young hot stars like HP Tau?
Studying protoplanetary disks around young hot stars like HP Tau is significant as these disks are believed to be the progenitors to planetary systems around stars, providing insights into the formation of planetary systems.
Today's Current Affairs brings us a stunning image captured by the Hubble Space Telescope, showcasing the triple star system HP Tau, HP Tau G2, and HP Tau G3. These young stars are only 10 million years old, with HP Tau yet to start fusing hydrogen. The image reveals a reflection nebula 550 light years away in Taurus, displaying a characteristic blue hue from the interstellar dust. This system is a prime example of protoplanetary disks, believed to be the building blocks of planetary systems around stars. Hubble continues to amaze us with its discoveries, reminding us of the wonders of the Universe.

Karnataka cities face alarming air pollution levels, with PM2.5 soaring six to seven times above WHO guidelines, raising serious health concerns.
A recent Greenpeace India report highlights alarming air quality issues in three major Karnataka cities: Bengaluru, Mangaluru, and Mysuru. The findings indicate that particulate matter (PM2.5 and PM10) levels in these cities are significantly higher than the World Health Organization’s guidelines. In areas like Hyderabad and Chennai, PM2.5 levels are six to seven times above…
