1. THE SIENA GALAXY ATLAS (SGA)
TAG: GS 3: SCIENCE AND TECHNOLOGY
THE CONTEXT: Recently, astronomers have created a stunning atlas of nearly 400,000 galaxies in the cosmic neighbourhood of the Milky Way, aptly named the Siena Galaxy Atlas (SGA).
THE SIENA GALAXY ATLAS (SGA):
- This remarkable feat was achieved using data from three astronomical surveys conducted between 2014 and 2017 at the Cerro Tololo Inter-American Observatory (CTIO) and Kitt Peak National Observatory (KPNO), collectively known as the DESI Legacy Surveys.
- The cosmic atlas is a digital atlas that was created to get to know our universe better through several of the known galaxies.
- NGC 520 is one of the largest and brightest galaxies in the Siena Galaxy Atlas. It is made of two disk galaxies that will eventually merge together to form one massive system.
- A selection of 42 galaxies from the Siena Galaxy Atlas illustrates the tremendous range of galaxy types, sizes, colours and surface brightness profiles, internal structure, and environments of the galaxies in the SGA.
- IC 4212 is a barred spiral galaxy located in the constellation Virgo. It is situated close to the celestial equator, meaning it is at least partly visible from both hemispheres in certain times of the year.
HOW IS IT DIFFERENT FROM OTHER ATLASES?
- It is dependent on state-of-the-art digital images captured by advanced technology, unlike previous atlases which relied on antiquated equipment and photographic plates.
- As it is built on the images captured with highly sensitive instruments, it boasts of having the most accurate data.
- It is also the first cosmic atlas to feature the light profiles of galaxies - a curve that describes how the brightness of the galaxy changes from its brightest point to its dimmest.
HOW DOES IT CONTRIBUTE TO OUR UNDERSTANDING OF THE UNIVERSE?
- Comprehensive and detailed view of nearby galaxies:
- The SGA provides a comprehensive and detailed view of nearly 400,000 galaxies in the cosmic neighbourhood of the Milky Way.
- This is a significant increase over previous atlases, which typically included only a few thousand galaxies.
- The SGA’s large sample size allows astronomers to study the statistical properties of galaxies in more detail, and to identify rare or unusual objects.
- High-quality data:
- The SGA is based on high-quality digital images captured with highly sensitive instruments.
- This results in much higher data quality than previous atlases, which were often based on photographic plates.
- The SGA’s high-quality data allows astronomers to make more accurate measurements of the sizes, shapes, colours, and luminosities of galaxies.
- Publicly available data:
-
- The SGA is freely available to the public online, anyone can access and use the data for their own research or educational purposes.
- The SGA’s public availability will help to democratize astronomy and encourage more people to participate in the scientific process.
