Astronomical images carry a lot of scientific information hidden within the beautiful colors, but even that’s only part of the story. A great deal of knowledge comes from analyzing the light as broken down into its spectrum. The specific colors and relative amounts of each color reveal information about temperature, what atoms are present, and the speed of the astronomical object being observed, which reveals the distances to far-off galaxies. For those reasons, spectroscopy is one of the essential tools of astronomy.
Center for Astrophysics | Harvard & Smithsonian scientists apply spectroscopy to every aspect of astronomy:
Hunting for absorption spectra in the atmospheres of exoplanets, using the next generation of telescopes. Future observatories such as the Giant Magellan Telescope (GMT) will be able to detect the spectrum from traces of oxygen and water, chemicals that are important for life as we know it. Potentially Habitable Super-Earth is a Prime Target for Atmospheric Study
Developing new spectrographs for the next-generation observatories, including the GMT. The GMT-Consortium Large Earth Finder (G-CLEF) is a precision spectrograph designed to measure Doppler effect red- and blueshifts for exoplanets, down to 10 centimeters per second, or less than a quarter of a mile per hour — about the rate an ant walks. CfA Research: http://gclef.cfa.harvard.edu/
Studying the spectrum of interesting environments, including the regions around newborn star systems. Astronomers use the Atacama Large Millimeter/submillimeter Array (ALMA) and other observatories to identify molecules from their spectrum. In that away, they identified an organic molecule in common between an infant star system and a comet in the Solar System. Astronomers Discover Traces of Methyl Chloride around Infant Stars and Nearby Comet
The Giant Magellan Telescope (GMT) will carry the G-CLEF spectrometer to study the atmospheres of exoplanets and perform other spectroscopic measurements. This computer-generated image shows the GMT at sunset, preparing for observations.
As Isaac Newton demonstrated in 1704, white light is a mixture of all the colors of the rainbow, which can be separated using a prism or — in the case of a real rainbow — a drop of water. In the 19th century, scientists realized they could identify different types of atom by the light they emitted. A group of astronomers even discovered the element helium by looking at the spectrum from the Sun, naming it for “Helios”, the Greek sun god.
Spectroscopy rapidly became a powerful tool in both chemistry and astronomy. The quantum theory of atoms provided an explanation for the unique spectrum of each element and molecule. Thanks to the particular interactions between the electrons and nuclei, each type of atom or molecule can only absorb or emit light of specific wavelengths, which are the physical property of light that gives its color. For instance, colors of neon, krypton, or sodium light bulbs are colored red, blue, and yellow because atoms of those elements emit most of their light in those wavelengths.
Today, astronomers use that quantum knowledge to build spectrographs, which split light into its component colors in a more precise way than Newton’s glass prism. By seeing which colors are emitted or absorbed, and the relative amounts of each wavelength, astronomers can identify the chemical composition of a star’s atmosphere or an interstellar nebula , along with the temperature and pressure of the gas.
Astronomers also use known spectra to measure the distance to galaxies. The universe is expanding, carrying galaxies along with it, so distant galaxies appear to be moving away from us. The light emitted by those galaxies is “redshifted”, meaning it’s stretched to longer wavelengths. The larger the redshift, the faster the galaxy seems to be moving, and the farther away it is. By identifying how much the spectrum of hydrogen from distant galaxies is redshifted, astronomers can measure the distance to those galaxies.
On a smaller scale, astronomers use spectroscopy to measure the the motion of a star in a binary star system, from an orbiting exoplanet, due to the tug of a black hole, or any number of other possibilities. The motion of the star toward us blueshifts the light slightly, moving it to shorter wavelengths, while moving away redshifts the light. This is the Doppler effect for light, the same essential phenomena produced when an ambulance siren changes pitch as it passes.
Researchers also do spectroscopy in the lab, studying the spectrum of different elements and molecules under a variety of conditions.
For example, experiments have determined that the relative strength of two emission lines in a spectrum provides an independent test of the temperature and density of the atoms making that spectrum. That in turn is useful for astronomical observations.
Astrochemists have also produced and studied complex organic molecules in the lab under simulated interstellar conditions. These molecules were later observed in space, confirming the experiments’ findings.
Laboratory research in astrochemistry studies how ionization changes the spectrum of atoms and molecules. Ionization in astronomy means stripping electrons away, turning the material into a plasma. This happens in many astronomical environments, including the atmospheres of stars, interstellar space, the region between galaxies in a galaxy cluster , and many other places. Using laboratory experiments and theoretical calculations, researchers develop methods of studying astronomical plasmas and the processes that made them.

A new, sensitive, and cost-effective lab-on-paper-based immunosensor was designed based on electrochemical impedance spectroscopy (EIS) for the detection of exosomes. EIS was selected as the determination method since there was a surface blockage in electron transfer by binding the exosomes to the transducer. Briefly, the carbon working electrode (WE) on the paper electrode (PE) was modified with gold particles (AuPs@PE) and then conjugated with anti-CD9 (Anti-CD9/AuPs@PE) for the detection of exosomes. Variables involved in the biosensor design were optimized with the univariate mode. The developed method presents the limit of detection of 8.7 × 10 2 exosomes mL −1 , which is lower than that of many other available methods under the best conditions. The biosensor was also tested with urine samples from cancer patients with high recoveries. Due to this a unique, low-cost, biodegradable technology is presented that can directly measure exosomes without labeling them for early cancer or metastasis detection.

LEXINGTON, Ky. — A hospital, a laboratory, three lab employees, and a referring physician and his office manager have agreed to collectively pay the United States more than $7.2 million dollars to resolve civil allegations that they defrauded federal healthcare programs in connection with laboratory tests that were not medically necessary or were tainted by violations of the federal Anti-Kickback Statute.
Physicians’ Medical Center, LLC (“PMC”), a hospital in New Albany, Indiana, operated a clinical laboratory that was managed by the now defunct United States Medical Scientific Indiana, LLC (“US Med Sci Indiana”). The United States alleged that PMC, through its lab manager’s fraudulent conduct, violated the False Claims Act by submitting false claims for laboratory services to Medicare, Kentucky Medicaid, and TRICARE, from December 2016 to September 2018.
Federal healthcare programs only pay for laboratory services that are used for medical diagnosis or treatment. As set forth in the settlement documents, the United States alleged that PMC billed Medicare, Kentucky Medicaid, and TRICARE for urine drug tests referred by various entities – including a homeless shelter and peer-to-peer recovery centers – that did not use the test results for medical diagnosis or treatment. These nonmedical entities only used the test results to monitor clients’ compliance with the conditions of their programs and with court orders. In total, the United States alleged that PMC submitted nearly $3 million in false claims to Medicare, Kentucky Medicaid, and TRICARE, for urine drug tests referred by these nonmedical entities.
Two lab employees also entered settlement agreements to resolve their False Claims Act liability, for causing PMC’s submission of false claims for lab tests from these nonmedical entities. The United States alleged that Bobby Sturgeon, a sales representative for PMC’s laboratory, knew that these entities did not provide medical services, but nonetheless pursued and worked with them as clients. And Sturgeon financially benefited from these fraudulent sales practices because his salary was based in part on the amount insurers paid PMC for his clients’ tests, including those from the nonmedical entities. Similarly, the United States alleged that Derrick Arthur, one of the peer-to-peer recovery center’s directors, worked as a specimen collector for PMC’s lab and helped arrange for a volunteer doctor to order urine drug testing, despite knowing that the doctor did not provide medical treatment to the center’s clients. By doing so, Arthur facilitated the improper billing of laboratory tests to federal healthcare programs.
After PMC closed its laboratory in October 2018, Sturgeon became a sales representative for Bluewater Toxicology, a laboratory in Mount Washington, Kentucky. As set forth in the settlement documents, Sturgeon then caused Bluewater to submit false claims for medically unnecessary urine drug tests, from the same peer-to-peer recovery centers and homeless shelter, through July 2019. Like PMC, Bluewater knew that federal healthcare programs would not pay for urine drug tests used for nonmedical purposes, but still submitted the claims for payment. In total, the United States alleged that Bluewater submitted nearly $450,000 in false claims to Medicare and Kentucky Medicaid for urine drug tests referred by the nonmedical entities. Bluewater, Sturgeon, and Arthur have entered settlement agreements resolving their liability for the submission of Bluewater’s false claims for tests from these nonmedical entities.
In a related scheme, Steve Moore, a laboratory sales representative for PMC and Bluewater Toxicology, allegedly paid a physician, Pablo Merced, M.D., and his wife and office manager, Theresa Merced, to induce referrals of laboratory tests to PMC and Bluewater Toxicology. To gain Dr. Merced’s large volume of referrals, Moore paid cash to the Merceds and paid additional salary to lab specimen collectors who worked at their office. PMC, through its lab manager, also employed specimen collectors in Dr. Merced’s medical practice, who were alleged to perform office work unrelated to their specimen collection duties. Moore’s cash payments and the PMC lab manager’s in-kind payments to the Merceds violated the Anti-Kickback Statute, 42 U.S.C. § 1320a-7b(b). PMC and Bluewater submitted millions of dollars of claims to federal healthcare programs for the lab tests that were tainted by their sales representative’s kickbacks. PMC, Moore, and the Merceds have entered settlement agreements resolving their liability for the submission of the false claims tainted by kickbacks.
PMC’s settlement agreement also resolved its False Claims Act liability for claims for lab tests referred by medical providers at Prescribe Recovery, a medical practice in Paris, Kentucky. The United States alleged that PMC’s lab manager, US Med Sci Indiana, actually owned Prescribe Recovery, and directed its medical providers’ referral of laboratory tests to PMC’s lab. As PMC’s lab manager, US Med Sci Indiana received 78% of the laboratory claim reimbursements paid to PMC, including the reimbursements from Prescribe Recovery. PMC’s payment of 78% of laboratory reimbursements to US Med Sci Indiana induced them (as the lab manager) to direct Prescribe Recovery’s lab referrals to PMC, and violated the Anti-Kickback Statute.
Collectively, these civil healthcare fraud settlements return more than $7.2 million to the Medicare, Kentucky Medicaid, and TRICARE programs. For their roles in the scheme as the laboratories submitting the false claims, PMC agreed to pay $5,219,000 and Bluewater Toxicology agreed to pay $895,952. Sturgeon and Moore, agreed to pay $713,466 and $40,000, respectively, to resolve their liability. Arthur agreed to pay $5,500 to resolve his liability; and Dr. and Mrs. Merced collectively agreed to pay $450,000 to resolve their liability, under the False Claims Act and Dr. Merced’s liability for separate conduct under the Controlled Substances Act. The value of Moore’s, Arthur’s, and the Merceds’ settlements included factoring in their inability to pay, based on financial disclosures.
“Through a complex patchwork of schemes, the federal government was defrauded out of millions of dollars,” said Carlton S. Shier, IV, United States Attorney for the Eastern District of Kentucky. “This money was appropriated to provide medical services to eligible Americans; instead, it improperly yielded proceeds to those who were submitting false claims. When fraud and abuse deplete these valuable resources, it injures all of us. With the assistance of our partners and the filing of a qui tam complaint, vital resources are now being returned to their intended purpose.”
“Individuals and entities participating in the federal health care system must comply with laws designed to protect program funds and ensure patients receive appropriate, quality care,” said Special Agent in Charge Kelly J. Blackmon of the U.S. Department of Health and Human Services Office of Inspector General (HHS-OIG). “We will continue to collaborate with our law enforcement partners to hold health care providers accountable for improper payments from federal health care programs.”
The settlements resolve a lawsuit brought by a private citizen under the qui tam provisions of the False Claims Act. Under those provisions, a private party can file a civil action on behalf of the United States, thereby bringing allegations of fraud to the Government’s attention, and share in any financial recovery. As part of this resolution, the individuals who filed the qui tam complaint will receive a portion of the settlement proceeds. The civil case is captioned United States ex rel. Clark et al. v. United States Medical Scientific, LLC, et al. , Case No. 0:18-cv-109-KKC.
The settlement agreements resulted from the joint efforts of the United States Attorney’s Office for the Eastern District of Kentucky; U.S. Department of Health and Human Services, Office of Inspector General; U.S. Drug Enforcement Administration; U.S. Department of Defense, Office of the Inspector General, Defense Criminal Investigative Service; and the Kentucky Attorney General’s Office of Medicaid Fraud and Abuse Control . The United States was represented by Assistant U.S. Attorney Meghan Stubblebine. The claims resolved by the settlements are allegations only, and there has been no determination of liability.
