Early detection of Sagittarius A* (Sgr A*) relied on radio astronomy due to the obscuring dust in the galactic center, initially identified as a bright radio source in the Sagittarius constellation.

Nova explosions, which were thought until now to be relatively simple, are actually turning out to be very different. An ...

For astronomers, one of the greatest challenges is capturing images of objects and phenomena that are difficult to see using optical (or visible light) telescopes. This problem has been largely ...

The wavelengths of radio light are so large that you can't capture a high-resolution image with a single dish. To capture an image as sharp as, say, the Hubble telescope, you'd need a radio dish tens ...

The first space mission led by the University of Michigan Department of Astronomy is scheduled to launch in 2029 with the support of a NASA grant worth $10 million. The mission is called ...

For more than 400 years, astronomers both professional and amateur have taken a special interest in observing Mira stars, a class of variable red giants famous for pulsations that last for 80-1,000 ...

New high-resolution images show that novae are anything but simple stellar fireworks. One exploded with multiple gas streams ...

The quantification of large optics demands metrology systems that operate in the context of turbulence, vibration and additional challenges. Figure 1. Measurement of large optics, such as this 8-meter ...

The GRAVITY instrument on ESO's Very Large Telescope Interferometer (VLTI) has made the first direct observation of an exoplanet using optical interferometry. This method revealed a complex ...
