'Like a family photo of our solar system': The James Webb telescope is watching 2 alien planets being born before our eyes
- The James Webb Space Telescope (JWST) is observing the formation of two alien planets around the star PDS 70, which is located about 370 light-years away.
- PDS 70b and PDS 70c are the two nascent planets being directly imaged through innovative approaches by researchers using JWST and the European Southern Observatory's Very Large Telescope (VLT).
- The JWST's Near Infrared Imager and Slitless Spectrograph (NIRISS) utilized Aperture Masking Interferometry to observe the planets in high resolution and detected potential material surrounding them.
- Observations with longer wavelengths by JWST indicated warm material around the planets, suggesting accretion from circumplanetary disks, which signals ongoing planet growth.
- The star PDS 70 is still actively accreting material at a young age of about 5.4 million years, offering a rare opportunity to witness planet formation in action.
- The study also hints at the presence of a third planet, PDS 70d, providing additional insights into the evolving planetary system.
- Further observations and follow-up studies are needed to confirm the nature of the third potential planet and understand its atmospheric composition.
- This research sheds light on the ongoing planet formation processes and the dynamic interactions within the PDS 70 planetary system.
- The findings contribute to our understanding of how planetary systems evolve and provide valuable insights into the mechanisms of planet growth and accretion.
- The ability to directly observe exoplanets and their formation using advanced telescopes like JWST opens up new opportunities for studying the origins of planetary systems.
- The discoveries made through these observations showcase the intricate and fascinating processes involved in the birth and evolution of planets around young stars.

One large Milky Way galaxy or many galaxies? 100 years ago, a young Edwin Hubble settled astronomy’s ‘Great Debate.’
- A century ago, Edwin Hubble expanded the known universe, revealing that the Andromeda nebula was distant from the Milky Way.
- Hubble's discoveries paved the way for exploring a vast universe containing trillions of galaxies.
- Early astronomers initially believed the Milky Way encompassed the entire universe.
- Nebulae were classified into gaseous regions, clusters of stars, and those with spiral structure like the Andromeda nebula.
- In the 'Great Debate,' astronomers debated whether spiral nebulae were small and within the Milky Way or distant galaxies.
- Hubble utilized Cepheid variables to calculate the distance to M31, determining it was much farther than previously thought.
- Hubble's discovery ended the debate about the Milky Way's size and the nature of nebulae.
- Hubble also observed the redshift indicating galaxies were moving away, leading to the understanding of an expanding universe.
- Georges Lemaitre proposed the idea of an expanding universe and the big bang theory.
- Hubble's legacy continues with NASA's Hubble Space Telescope and advancements in studying galaxies, reaching billions of light years away.
