Hubble views lenticular galaxy NGC 5283

The lenticular galaxy NGC 5283 is the subject of this NASA Hubble Space Telescope image. NGC 5283 contains an active galactic nucleus, or AGN. An AGN is an extremely bright region at the heart of a galaxy where a supermassive ...

Hubble spots energetic galaxy NGC 547

This NASA Hubble Space Telescope image reveals NGC 547, an elliptical galaxy that sits about 250 million light-years away from Earth in the constellation Cetus. NGC 547 shines just below the center of this image, with its ...

Hubble observes lenticular galaxy NGC 3489

NASA's Hubble Space Telescope captured this image of the lenticular galaxy NGC 3489. Lenticular galaxies aren't quite spiral galaxies or elliptical galaxies. They lie somewhere in between, exhibiting traits of both. Lenticular ...

Structural insight into process of gene regulation

In the cell nucleus, numerous proteins bind to the DNA molecule in order to regulate the activity of certain genes. One of these is the TATA-box binding protein (TBP), which binds to a specific DNA sequence and constitutes ...

Building better superconductors with palladium

It is one of the most exciting races in modern physics: How can we produce the best superconductors that remain superconducting even at the highest possible temperatures and ambient pressure? In recent years, a new era of ...

Study finds new pathway for clearing misfolded proteins

Misfolded proteins are toxic to cells. They disrupt normal functions and cause some age-related human degenerative diseases, like Alzheimer's, Parkinson's, and Huntington's diseases. Cells work constantly to eliminate misfolded ...

Visualizing differences in nuclear structure

Helium usually has two protons and two neutrons strongly bound to each other, often forming a substructure within the nucleus. A nucleus composed of several such substructures is called a cluster structure. In the standard ...

DNA packaging supports cell division, finds study

The DNA molecule is located in the cell nucleus as a densely packed complex of DNA and protein, known as chromatin. Wrapped in sections around a core of special proteins known as histones, the DNA forms so-called nucleosomes, ...
