NGC 4414 (also known as UGC 7539) is a massive unbarred spiral galaxy of some 56,000 light-years in diameter, located about 62.3 million light-years away in the constellation Coma Berenices. NGC 4414 is a huge unbarred spiral galaxy. It moves at approximately 716 kilometers per second. It is located about 62.3 million light-years away from the constellation Coma Berenices

NGC 4414 can be characterized by a regularly rotating inner H i disk, and a more disturbed outer disk. While it is moving away from us at approximately 716 kilometers per second. It is a member of the Coma I group of galaxies, very close to the Virgo Cluster.

HIP 65426 b is a huge gas giant. It is discovered by the European Southern Observatory's Telescope. It is a hot Jupiter exoplanet. The mass of HIP 65426 b is 6-12 times bigger than Jupiter. HIP 65426 b is clouded with dust, it has a thick clouded atmosphere that has a temperature of 1,800 to 2,500 degrees Fahrenheit. It orbits a hot, young star, it might be a failed star, and it has a companion, now is its host star which prevents it from gathering sufficient mass. In this picture of HIP 65426, they blocked the starlight in the middle for us to see the giant companion.

HIP 65426b was discovered by a group of astronomers and researchers from the Max Planck Institute for Astronomy and its host system.
HIP 65426 is about 14 million years old, it is part of the Scorpius-Centaurus association, it contains between 3000 and 5000 stars and it is at a distance of almost 400 light-years from Earth. However, the planet HIP 65426b is about 1.5 times the radius of Jupiter, with a solid core and thick layers of (mostly hydrogen) gas. The outside part appears to have water vapor and reddish clouds, similar to Jupiter's. The planet is far out, orbiting its host star at 100 astronomical units.

https://en.wikipedia.org/wiki/Carina_Nebula

The Carina Nebula is part of the Sagittarius-Carina arm of the Milky Way, there are more than 14,000 stars in the region.Carina Nebula is also called the Grand Nebula. It is a large Nebula, with a complex area of bright in the constellation Carina. The distance between Carina Nebula and the earth is approximately 8,500 light-years. The nebula has the large Carina OB1 association and several related open clusters within its boundaries The nebula is one of the largest diffuse nebulae in our skies.
