Possible black hole
at center of galaxy
PHOENIX. Ariz (AP) St;irv that /ip along at high speeds and
bursts of infrared radiation lend new support to the theorv that a
Mark, hole the size of a million suns lies at the center of the Milkv
Way. the galactic home of the Earth
The research, presented Tuesday by two Umversilv of Arizona
astronomers, strengthens tin* notion that a massive fxidv exerting a
powerful gravitational pull is centered on an obje< I known as the
Sgr-A-Star located in the (.ore of the Milkv Wav iJH.ono light years
away.
One of the astronomers, l aird ('.lose, said a new instrument has
detected for the first time streams of infrared radiation from Sgr A
Star The finding of infrared radiation is consistent with the pres
uni e of a hint k hole in the Milkv W av s i ore
"We have detected a source of infrared, whiih is powerful evi
dence that there is a huge object, likelv a him k hole, at the i enter
of the Milkv Way. ( lose said at a news ronferem e
The research used a telescope that lakes out the twinkle of stars
caused hv atmosphere distortion, and can pinpoint infrared radi
ation from Sgr-A-Star The present e ot sin h radiation is i oltsidered
critical evideuce of a iliac k hole Infrared radiation would he goner
ated as gas and other material tails at an accelerating rate toward
the center of a blar k hole.
Another Arizona astronomer, loseph Haller, measured the move
iTient and concentration of stars m the gal.ntn core and found
more evidence for a black hole
He said the stndv showed that stars within about four trillion
miles of Sgr-A-Star had a< i elerated to almost a ipiarter ol a million
miles an hour, a movement that i mild lie caused onlv hv a power
ful gravitational attrui turn
Haller said he also measured the mass of material m ar Sgr \
Star and determined that within 0 7 to 1 fi light vears around the
object the mass was equal to about TOO.00(1 suns
"That amount of mass is consistent with the idea that Sgi A Star
is a black hole.” said Haller
A light year, the distance light will travel in one year m a vacu
mu, is about six trillion miles
University of Illinois astronomer Kwok Yung l.o said that al
though the observations were important, thev fell short ol present
ing proof of a bloc k hole at the Sgr A Star
Studies of Sgr-A-Star show that it is a verv small bodv and vet
appears In have a massive gravitational pull, he said This is con
sistent with a bla< k hole
Sgr-A-Star also emits a radio signal that astronomers s.iv is the
tv pe of emission that would be expec ted from a blat k hole
To prove it is a hint k hole, however, said l.o. astronomers need
to show that the mass of Sgr-A-Star is equal to about one million
suns within an area about two million miles across. Sui h a i mu en
trillion of matter would t reate a gravitational pull so powerful that
nothing could esi ape. not even light This is the i har.K teristu that
gives blai k holes their name
I taller agreed.
"To determine that this is a blai k hole, we need to gel in much
much closer." he said
