Sun’s magnetic field originates surprisingly close to the surface

On May 22, 2024 an international team of researchers, including CIERA Professor Daniel Lecoanet, published a paper in Nature that brings scientists closer than ever before to solving a 400-year-old solar mystery that stumped even famed astronomer Galileo Galilei. Since first observing the sun’s magnetic activity, astronomers have struggled to pinpoint where the process originates.

Witch Head Nebula and Rigel

Witch Head Nebula and Rigel

Near Rigel, a bright star found in the constellation Orion, lies the Witch Head Nebula (look closely to see the face!). This nebula is a reflection nebula– a cloud of dust that is lit up by nearby stars. Rigel’s starlight reflects off the dust to light up this very faint nebula. Photographer and CIERA graduate

Elephant’s Trunk Nebula

Photographer and CIERA graduate student Imran Sultan captured the Elephant’s Trunk Nebula (IC 1396) over two nights (July 9-10, 2023) from the bright skies of the Chicago suburbs. Observing the Elephant’s Trunk reveals emission from the ionized gas in the star-forming region, shown here in the HOO color palette. Sultan was able to overcome light

Pillars of Creation

The swirling oranges and sparkling refractions of light in this photo, captured by CIERA graduate student Imran Sultan, are the Pillars of Creation in the Eagle Nebula. The Pillars of Creation are part of an active star-forming region within the nebula and hide newborn stars in their cloud-like columns. This sight was captured from Bortle

Orion’s Dream

When looking up into the sky, one of the first constellations many see is Orion, made up of three bright stars, one of which is the 11th brightest star in the sky. This photo of the Orion constellation, which also features the Great Orion Nebula and Horsehead/Flame Nebulae, was captured by CIERA graduate student Imran

This photo, captured by CIERA graduate student Imran Sultan, is a widefield shot of the interstellar gas and dust in the Cepheus constellation, prominently featuring the Shark Nebula. Interstellar gas is composed primarily of hydrogen, followed by helium with trace amounts of carbon, oxygen, and nitrogen. These clouds’ glowing nature is credited to the fluorescence

Lion Nebula SH2-132

The purple and blue hues in this photo highlight the Lion Nebula, which was shot in the last two nights of July 2023 in dual narrowband (H-alpha and O III) in Illinois. This image was taken by Imran Sultan, a graduate student in CIERA Professor Claude-Andre Faucher-Giguere’s group who practices astrophotography in his free time.

Heart and Soul Nebulae

This is a wide-field view of the Heart and Soul Nebulae in the constellation Cassiopeia. Captured by CIERA graduate student Imran Sultan from Bortle Class 8-9 city skies over three nights in dual narrowband (H-alpha and O III).

Sadr Region, Butterfly Nebula, and Crescent Nebula

This emission around Sadr (including the Butterfly and Crescent nebulae), was captured by Imran Sultan from Bortle Class 8-9 city skies in narrowband, a filter that allows astronomers to isolate particular emission lines of gasses in astronomical objects. The Bortle Class scale measures the brightness of the night sky, with 8-9 signifying that the sky

Brightest gamma-ray burst of all time came from the collapse of a massive star

In October 2022, an international team of researchers, including Northwestern University astrophysicists, observed the brightest gamma-ray burst (GRB) ever recorded, GRB 221009A. In a paper published in April 2024, a team led by CIERA Postdoctoral Fellow Peter Blanchard has confirmed that the phenomenon responsible for the historic burst — dubbed the B.O.A.T. (“brightest of all time”)

Unprecedented gamma-ray burst explained by long-lived jet

Last year, Northwestern University researchers uncovered new observational evidence that long gamma-ray bursts (GRBs) can result from the merger of a neutron star with another compact object (either another neutron star or black hole) — a finding that was previously believed to be impossible. Now, another Northwestern team offers a potential explanation for what generated

‘Twinkle, Twinkle, Little Star’ passed through massive stars

A Northwestern University-led team of researchers, including postdoctoral fellow Evan Anders, developed the first 3D simulations of energy rippling from a massive star’s core to its outer surface. Using these new models, the researchers determined, for the first time, how much stars should innately twinkle. Depending on how large or bright a massive star is,
