The initial detection of radio waves from the astronomical object was created in the 1930s when Karl Jansky observed radiation coming back from the extragalactic nebula. Subsequent observations have ...

We are staring "right down the barrel of it, which is really quite surprising to me — we're just lucky." One of the most photographed objects in the night sky is the Ring Nebula, wreckage of a ...

The Ring Nebula is perhaps one of the most photographed objects in the night sky, dating back to its first image in 1886. Its intrinsic structure has been debated for as long as it has been observed.

This course provides an overview of extragalactic astronomy with an emphasis on the development of large-scale structures and galaxy formation. The first part of the course deals with the development ...

Interplanetary scintillation (IPS) refers to random fluctuations in radio intensity of distant small-diameter celestial object, over time periods of the order of 1 s. The scattering and scintillation ...

The team started with the Cosmic Evolution Early Release Science (CEERS) survey before widening their scope to other extragalactic legacy fields, including the JWST Advanced Deep Extragalactic Survey ...

The evolution of white dwarfs is essentially a gravothermal process of cooling in which the basic ingredients for predicting their evolution are well identified, although not always well understood.

Part of the JWST Advanced Deep Extragalactic Survey, the event highlights how th... The white dwarf star RX J0648.0–4418, 1,700 light-years away, spins at a rapid pace of 13 seconds per rotation.

Once dismissed as a nearby “spiral nebula” measurements of Andromeda with its embedded Cepheid star served ... who spectroscopically studied the “spiral nebulae” a decade before Hubble. Slipher did ...
